I want all my lost access yahoo account 'delete'; Requesting supporter for these old account deletion; 'except' my Newest yahoo account this Account don't delete! Because I don't want it interfering my online 'gamble' /games/business/data/ Activity , because the computer/security program might 'scure' my Information and detect theres other account; then secure online activities/ business securing from my suspicion because of my other account existing will make the security program be 'Suspicious' until I'm 'secure'; and if I'm gambling online 'Depositing' then I need those account 'delete' because the insecurity 'Suspicioun' will program the casino game 'Programs' securities' to be 'secure' then it'll be 'unfair' gaming and I'll lose because of the insecurity can be a 'Excuse'. Hope y'all understand my explanation!

Repair the Yahoo Search App.
Yahoo Search App from the Google Play Store on my Samsung Galaxy S8+ phone stopped working on May 18, 2018.
I went to the Yahoo Troubleshooting page but the article that said to do a certain 8 steps to fix the problem with Yahoo Services not working and how to fix the problem. Of course they didn't work.
I contacted Samsung thru their Samsung Tutor app on my phone. I gave their Technican access to my phone to see if there was a problem with my phone that stopped the Yahoo Search App from working. He went to Yahoo and I signed in so he could try to fix the Yahoo Search App not working. He also used another phone, installed the app from the Google Play Store to see if the app would do any kind of search thru the app. The Yahoo Search App just wasn't working.
I also had At&t try to help me because I have UVERSE for my internet service. My internet was working perfectly. Their Technical Support team member checked the Yahoo Search App and it wouldn't work for him either.
We can go to www.yahoo.com and search for any topic or website. It's just the Yahoo Search App that won't allow anyone to do web searches at all.
I let Google know that the Yahoo Search App installed from their Google Play Store had completely stopped working on May 18, 2018.
I told them that Yahoo has made sure that their Yahoo members can't contact them about anything.
I noticed that right after I accepted the agreement that said Oath had joined with Verizon I started having the problem with the Yahoo Search App.

How Bitcoin Mining Works
Where do bitcoins come from? With paper money, a government decides when to print and distribute money. Bitcoin doesn't have a central government.
With Bitcoin, miners use special software to solve math problems and are issued a certain number of bitcoins in exchange. This provides a smart way to issue the currency and also creates an incentive for more people to mine.
Bitcoin is Secure
Bitcoin miners help keep the Bitcoin network secure by approving transactions. Mining is an important and integral part of Bitcoin that ensures fairness while keeping the Bitcoin network stable, safe and secure.

Bitcoin mining is the process of adding transaction records to Bitcoin's public ledger of past transactions or blockchain. This ledger of past transactions is called the block chain as it is a chain of blocks. The block chain serves to confirm transactions to the rest of the network as having taken place.
Bitcoin nodes use the block chain to distinguish legitimate Bitcoin transactions from attempts to re-spend coins that have already been spent elsewhere.
What is Bitcoin Mining?
What is the Blockchain?
Bitcoin mining is intentionally designed to be resource-intensive and difficult so that the number of blocks found each day by miners remains steady. Individual blocks must contain a proof of work to be considered valid. This proof of work is verified by other Bitcoin nodes each time they receive a block. Bitcoin uses the hashcash proof-of-work function.
The primary purpose of mining is to allow Bitcoin nodes to reach a secure, tamper-resistant consensus. Mining is also the mechanism used to introduce Bitcoins into the system: Miners are paid any transaction fees as well as a "subsidy" of newly created coins.
This both serves the purpose of disseminating new coins in a decentralized manner as well as motivating people to provide security for the system.
Bitcoin mining is so called because it resembles the mining of other commodities: it requires exertion and it slowly makes new currency available at a rate that resembles the rate at which commodities like gold are mined from the ground.
What is Proof of Work?
A proof of work is a piece of data which was difficult (costly, time-consuming) to produce so as to satisfy certain requirements. It must be trivial to check whether data satisfies said requirements.
Producing a proof of work can be a random process with low probability, so that a lot of trial and error is required on average before a valid proof of work is generated. Bitcoin uses the Hashcash proof of work.
What is Bitcoin Mining Difficulty?
The Computationally-Difficult Problem
Bitcoin mining a block is difficult because the SHA-256 hash of a block's header must be lower than or equal to the target in order for the block to be accepted by the network.
This problem can be simplified for explanation purposes: The hash of a block must start with a certain number of zeros. The probability of calculating a hash that starts with many zeros is very low, therefore many attempts must be made. In order to generate a new hash each round, a nonce is incremented. See Proof of work for more information.
The Bitcoin Network Difficulty Metric
The Bitcoin mining network difficulty is the measure of how difficult it is to find a new block compared to the easiest it can ever be. It is recalculated every 2016 blocks to a value such that the previous 2016 blocks would have been generated in exactly two weeks had everyone been mining at this difficulty. This will yield, on average, one block every ten minutes.
As more miners join, the rate of block creation will go up. As the rate of block generation goes up, the difficulty rises to compensate which will push the rate of block creation back down. Any blocks released by malicious miners that do not meet the required difficulty target will simply be rejected by everyone on the network and thus will be worthless.
The Block Reward
When a block is discovered, the discoverer may award themselves a certain number of bitcoins, which is agreed-upon by everyone in the network. Currently this bounty is 25 bitcoins; this value will halve every 210,000 blocks. See Controlled Currency Supply.
Additionally, the miner is awarded the fees paid by users sending transactions. The fee is an incentive for the miner to include the transaction in their block. In the future, as the number of new bitcoins miners are allowed to create in each block dwindles, the fees will make up a much more important percentage of mining income.

Youtube Celeb Nicholas Merten Makes Big Bitcoin Prediction

Youtube Celeb Nicholas Merten Makes Big Bitcoin Prediction
Cryptocurrency influencer joins bulls with a $50,000 end of year valuation for Bitcoin based on failings in the fiat market.
Merten Says Bitcoin will go to $50,000 in 2018
Nicholas Merten, whose dedicated Youtube channel ‘data dash’ has nearly 300,000 followers, is an entrepreneur and investor in the crypto space with a wide-reaching influence who occupies a position somewhere between John McAfee and Tom Lee. When he tweets his opinions and predictions to his over 34,000 followers he can cause a change in trends.
His latest prediction that has Bitcoin at more than double it’s 2017 high by the end of the year relies on some major failings in the fiat market. In his Tweet Merten lists four factors he believes will push the price of Bitcoin up to highs never before seen.
My predictions for 2018:#Bitcoin will be $50K by the EOY. Why?
– Interest rates will continue to rise
– Deutsche Bank will go under by the 2018
– Equities and housing prices will take a massive hit
– With trillions of $'s that need to exit, the SEC will create a Bitcoin ETF
— Nicholas Merten (@Nicholas_Merten) May 27, 2018
Merten is a known crypto evangelist but even a few of his followers questioned his reasoning in the tweet. A follower who uses the handle Sammy Tommy pointed out that interest rates have no correlation with cryptocurrency prices and that though Deutsche Bank is restructuring, there is no way a bank of that size is going under by the end of the year.
When another follower asked for his prediction on the year-end crypto market cap Merten wrote that in his model it should go to $1 trillion. Among market predictors, Merten seems to occupy the middle ground between the antics of John McAfee who trades on his image of being a maverick in any space he occupies (Merten also shows himself on Twitter with guns) and the Tom Lees and Brian Kellys who bring a more traditional buttoned-down aspect to market predictions when they appear on shows like CNCB’s Fast Money.
Bulls Predicting Prices from $15,000 – $100,000
No matter if they are talking about the collapse of fiat banks or soberly discussing their charts and graphs all of these bulls are calling for a big number for Bitcoin in the fourth quarter. Despite Bitcoin falling below $8,000 again over the last week, Tom Lee sticks by his year-end prediction of $25,000 which relies on regulation clarity to open up the floodgates of institutional money.
Oddly John McAfee, who has promised to eat his own manhood live if Bitcoin doesn’t reach $1 million in 2020, is calling for Bitcoin to reach $15,000 by June which he says will be on track to meet his million dollar prediction according to his magic algorithms.
Though $50,000 is at the high end of the prediction spectrum it’s only half of the high point, CEO of China’s first Bitcoin exchange, Bobby Lee, called for when he said Bitcoin will end the year at a $100,000 double that and reach a million which would mean Lambos for all and save John Mcafee from a very awkward meal.

What is Bitcoin?
With the Bitcoin price so volatile everyone is curious. Bitcoin, the category creator of blockchain technology, is the World Wide Ledger yet extremely complicated and no one definition fully encapsulates it. By analogy it is like being able to send a gold coin via email. It is a consensus network that enables a new payment system and a completely digital money.
It is the first decentralized peer-to-peer payment network that is powered by its users with no central authority or middlemen. Bitcoin was the first practical implementation and is currently the most prominent triple entry bookkeeping system in existence.
Beware of the confusingly similar Bcash, BCH, Bitcoin Cash project.

Who created Bitcoin?
The first Bitcoin specification and proof of concept was published in 2009 by an unknown individual under the pseudonym Satoshi Nakamoto who revealed little about himself and left the project in late 2010. The Bitcoin community has since grown exponentially.
Satoshi's anonymity often raises unjustified concerns because of a misunderstanding of Bitcoin's open-source nature. Everyone has access to all of the source code all of the time and any developer can review or modify the software code. As such, the identity of Bitcoin's inventor is probably as relevant today as the identity of the person who invented paper.
Who is involved in Bitcoin?
Over $1B of investment into Bitcoin and blockchain companies has taken place resulting in thousands of companies and hundreds of thousands of individuals involved from around the world.
What is the Blockchain?
Who controls the Bitcoin network?
Nobody owns the Bitcoin network much like no one owns the technology behind email or the Internet. Bitcoin transactions are verified by Bitcoin miners which has an entire industry and Bitcoin cloud mining options. While developers are improving the software they cannot force a change in the Bitcoin protocol because all users are free to choose what software and version they use.
In order to stay compatible with each other, all users need to use software complying with the same rules. Bitcoin can only work correctly with a complete consensus among all users. Therefore, all users and developers have a strong incentive to protect this consensus.
How does Bitcoin work?
From a user perspective, Bitcoin is nothing more than a mobile app or computer program that provides a personal Bitcoin wallet and enables a user to send and receive bitcoins.
Behind the scenes, the Bitcoin network is sharing a massive public ledger called the "block chain". This ledger contains every transaction ever processed which enables a user's computer to verify the validity of each transaction. The authenticity of each transaction is protected by digital signatures corresponding to the sending addresses therefore allowing all users to have full control over sending bitcoins.
Thus, there is no fraud, no chargebacks and no identifying information that could be compromised resulting in identity theft. To learn more about Bitcoin, you can consult the original Bitcoin whitepaper, read through the extremely thorough Frequently Asked Questions, listen to a Bitcoin podcast or read the latest Bitcoin news.
Sponsors for free Bitcoins
Many people new to Bitcoin are curious about how to get some. Bitcoin faucets, places where bitcoins are given away for free, have been a part of spreading Bitcoin since the earliest days. But one problem is running out of bitcoins to give! That is why we have figured out a sustainable way to give away free bitcoins with sponsors.
Getting started with Bitcoin
Using Bitcoin to pay and get paid is easy and accessible to everyone.
1. Inform yourself
Bitcoin is different than what you know and use every day. Before you start using Bitcoin, there are a few things that you need to know in order to use it securely and avoid common pitfalls.
2. Choose your wallet
You can bring a Bitcoin wallet in your everyday life with your mobile or you can have a wallet only for online payments on your computer. In any case, choosing your wallet can be done in a minute.
3. Get Bitcoin
You can get Bitcoin by accepting it as a payment for goods and services. There are also several ways you can buy Bitcoin.
4. Spend Bitcoin
There is a growing number of services and merchants accepting Bitcoin all over the world. You can use Bitcoin to pay them and rate your experience to help honest businesses to gain more visibility.
1. Inform yourself
Bitcoin does not require merchants to change their habits. However, Bitcoin is different than what you know and use every day. Before you start using Bitcoin, there are a few things that you need to know in order to use it securely and avoid common pitfalls.
2. Processing payments
You can process payments and invoices by yourself or you can use merchant services and deposit money in your local currency or bitcoins. Most point of sales businesses use a tablet or a mobile phone to let customers pay with their mobile phones.
3. Accounting and taxes
Merchants often deposit and display prices in their local currency. In other cases, Bitcoin works similarly to a foreign currency. To get appropriate guidance regarding tax compliance for your own jurisdiction, you should contact a qualified accountant.
4. Gaining visibility
There is a growing number of users searching for ways to spend their bitcoins. You can submit your business in online directories to help them easily find you. You can also display the Bitcoin logo on your website or your brick and mortar business.
How does Bitcoin work?
This is a question that often causes confusion. Here's a quick explanation!
The basics for a new user
As a new user, you can get started with Bitcoin without understanding the technical details. Once you have installed a Bitcoin wallet on your computer or mobile phone, it will generate your first Bitcoin address and you can create more whenever you need one. You can disclose your addresses to your friends so that they can pay you or vice versa. In fact, this is pretty similar to how email works, except that Bitcoin addresses should only be used once.
Balances - block chain
The block chain is a shared public ledger on which the entire Bitcoin network relies. All confirmed transactions are included in the block chain. This way, Bitcoin wallets can calculate their spendable balance and new transactions can be verified to be spending bitcoins that are actually owned by the spender. The integrity and the chronological order of the block chain are enforced with cryptography.
Transactions - private keys
A transaction is a transfer of value between Bitcoin wallets that gets included in the block chain. Bitcoin wallets keep a secret piece of data called a private key or seed, which is used to sign transactions, providing a mathematical proof that they have come from the owner of the wallet. The signature also prevents the transaction from being altered by anybody once it has been issued. All transactions are broadcast between users and usually begin to be confirmed by the network in the following 10 minutes, through a process called mining.
Processing - mining
Mining is a distributed consensus system that is used to confirm waiting transactions by including them in the block chain. It enforces a chronological order in the block chain, protects the neutrality of the network, and allows different computers to agree on the state of the system. To be confirmed, transactions must be packed in a block that fits very strict cryptographic rules that will be verified by the network. These rules prevent previous blocks from being modified because doing so would invalidate all following blocks. Mining also creates the equivalent of a competitive lottery that prevents any individual from easily adding new blocks consecutively in the block chain. This way, no individuals can control what is included in the block chain or replace parts of the block chain to roll back their own spends.
Going down the rabbit hole
This is only a very short and concise summary of the system. If you want to get into the details, you can read the original paper that describes the system's design, read the developer documentation, and explore the Bitcoin wiki.
What is Bitcoin?
Bitcoin is a new currency that was created in 2009 by an unknown person using the alias Satoshi Nakamoto. Transactions are made with no middle men – meaning, no banks! Bitcoin can be used to book hotels on Expedia, shop for furniture on Overstock and buy Xbox games. But much of the hype is about getting rich by trading it. The price of bitcoin skyrocketed into the thousands in 2017.
Why Bitcoins?
Bitcoins can be used to buy merchandise anonymously. In addition, international payments are easy and cheap because bitcoins are not tied to any country or subject to regulation. Small businesses may like them because there are no credit card fees. Some people just buy bitcoins as an investment, hoping that they’ll go up in value.
Acquiring Bitcoins
Buy on an Exchange
Many marketplaces called “bitcoin exchanges” allow people to buy or sell bitcoins using different currencies. Coinbase is a leading exchange, along with Bitstamp and Bitfinex. But security can be a concern: bitcoins worth tens of millions of dollars were stolen from Bitfinex when it was hacked in 2016.
Transfers
People can send bitcoins to each other using mobile apps or their computers. It’s similar to sending cash digitally.
Mining
People compete to “mine” bitcoins using computers to solve complex math puzzles. This is how bitcoins are created. Currently, a winner is rewarded with 12.5 bitcoins roughly every 10 minutes.
Owning Bitcoins
Bitcoins are stored in a “digital wallet,” which exists either in the cloud or on a user’s computer. The wallet is a kind of virtual bank account that allows users to send or receive bitcoins, pay for goods or save their money. Unlike bank accounts, bitcoin wallets are not insured by the FDIC.
Wallet in cloud: Servers have been hacked. Companies have fled with clients’ Bitcoins.
Wallet on computer: You can accidentally delete them. Viruses could destroy them.
Though each bitcoin transaction is recorded in a public log, names of buyers and sellers are never revealed – only their wallet IDs. While that keeps bitcoin users’ transactions private, it also lets them buy or sell anything without easily tracing it back to them. That’s why it has become the currency of choice for people online buying drugs or other illicit activities.
Future in question
No one knows what will become of bitcoin. It is mostly unregulated, but some countries like Japan, China and Australia have begun weighing regulations. Governments are concerned about taxation and their lack of control over the currency.
Bitcoin worth $9M buried in garbage dump
Hoarders everywhere may be feeling smug after a British man threw a hard drive containing more than $9 million in bitcoin into the trash.
Bitcoin worth almost as much as gold
Bitcoin prices have surged to a high of $1,242. That makes the virtual currency only slightly less expensive than an ounce of gold.
Senate takes a close look at Bitcoin
Bitcoins are hotter than ever. Now a U.S. Senate panel is taking a close look at the digital currency.

Your search engine does not find any satisfactory results for searches. It is too weak. Also, the server of bing is often off

I want all my lost access yahoo account 'delete'; Requesting supporter for these old account deletion; 'except' my Newest yahoo account this Account don't delete! Because I don't want it interfering my online 'gamble' /games/business/data/ Activity , because the computer/security program might 'scure' my Information and detect theres other account; then secure online activities/ business securing from my suspicion because of my other account existing will make the security program be 'Suspicious' until I'm 'secure'; and if I'm gambling online 'Depositing' then I need those account 'delete' because the insecurity 'Suspicioun' will program the casino game 'Programs' securities' to be 'secure' then it'll be 'unfair' gaming and I'll lose because of the insecurity can be a 'Excuse'.

Question on a link
In the search for Anaïs Nin, one of the first few links shows a picture of a man. Why? Since Nin is a woman, I can’t figure out why. Can you show some reason for this? Who is he? If you click on the picture a group of pictures of Nin and no mention of that man. Is it an error?
Repair the Yahoo Search App.
Yahoo Search App from the Google Play Store on my Samsung Galaxy S8+ phone stopped working on May 18, 2018.
I went to the Yahoo Troubleshooting page but the article that said to do a certain 8 steps to fix the problem with Yahoo Services not working and how to fix the problem. Of course they didn't work.
I contacted Samsung thru their Samsung Tutor app on my phone. I gave their Technican access to my phone to see if there was a problem with my phone that stopped the Yahoo Search App from working. He went to Yahoo and I signed in so he could try to fix the Yahoo Search App not working. He also used another phone, installed the app from the Google Play Store to see if the app would do any kind of search thru the app. The Yahoo Search App just wasn't working.
I also had At&t try to help me because I have UVERSE for my internet service. My internet was working perfectly. Their Technical Support team member checked the Yahoo Search App and it wouldn't work for him either.
We can go to www.yahoo.com and search for any topic or website. It's just the Yahoo Search App that won't allow anyone to do web searches at all.
I let Google know that the Yahoo Search App installed from their Google Play Store had completely stopped working on May 18, 2018.
I told them that Yahoo has made sure that their Yahoo members can't contact them about anything.
I noticed that right after I accepted the agreement that said Oath had joined with Verizon I started having the problem with the Yahoo Search App.
No matter what I search for or website thru the Yahoo Search App it says the following after I searched for
www.att.com.
WEBPAGE NOT AVAILABLE

could not be loaded because:
net::ERR_CLEARTEXT_NOT_PERMITTED
I tried to search for things like www.homedepot.com. The same thing happened. It would say WEBPAGE NOT AVAILABLE. The only thing that changed were all the upper and lower case letters, numbers and symbols.
Then it would again say
could not be loaded because:
net::ERR_CLEARTEXT_NOT_PERMITTED
This is the same thing that happened when Samsung and At&t tried to do any kind of searches thru the Yahoo Search App.
Yahoo needs to fix the problem with their app.
