Do not use URL shortening services: always submit the real link. Begging/asking for bitcoins is absolutely not allowed, no matter how badly you need the bitcoins. Only requests for donations to large, recognized charities are allowed, and only if there is good reason to believe that the person accepting bitcoins on behalf of the charity is trustworthy. News articles that do not contain the word "Bitcoin" are usually off-topic. This subreddit is not about general financial news. Submissions that are mostly about some other cryptocurrency belong elsewhere. For example, /r/CryptoCurrency is a good place to discuss all cryptocurrencies.

For example, submissions like "Buying 100 BTC" or "Selling my computer for bitcoins" do not belong here. /r/Bitcoin is primarily for news and discussion. Please avoid repetition /r/bitcoin is a subreddit devoted to new information and discussion about Bitcoin and its ecosystem. New merchants are welcome to announce their services for Bitcoin, but after those have been announced they are no longer news and should not be re-posted. Aside from new merchant announcements, those interested in advertising to our audience should consider Reddit's self-serve advertising system .

Revealing Your Digital Currency Holdings Online Is A Horrible Idea

Revealing Your Digital Currency Holdings Online Is A Horrible Idea

Revealing Your Digital Currency Holdings Online Is a Horrible Idea This week a cryptocurrency trader who traded altcoins and bitcoin on the digital currency exchange Bittrex lost over 7 BTC ($18,000 USD) while recording the entire theft. The trader from New Zealand revealed his testimony and believes he was hacked by malicious bots created to steal digital assets. Also Read: GPU Shortage Intensifies as Cryptocurrency Mining Offers up to Twice the Average Russian Monthly Wage A trader named Shayne who calls himself Crypto is Key detailed an unusual experience watching his Bittrex account that held eleven BTC drain down to four BTC. The victim explains the Bittrex account was shared with a buddy of his who helped him make decisions and trades. Additionally, he says the account was protected with two-factor authentication and a very long password. However, when he woke up and logged into Bittrex, he noticed his holding were being sold, and his account was missing 7 BTC which was withdrawn to an unknown address. Everyones worst nightmare concerning trading is losing their wealth to thieves, explains the Bittrex trader. Last night I was in the nightmare, and whats worse is I had to fight while they tried to take my last four Bitcoin. Shayne Vows to Never Store Large Amounts of Digital Currency on Exchanges During the recorded video the trader and his buddy were logged into the Bittrex account while the thief was siphoning his digital assets. The victim thought the hacker might have been a bot or script program that worked very fast to sell his altcoins at spot price and then withdrew the bitcoins after each sale.

Configuring Coinbase

Modified on: Mon, 11 Sep, 2017 at 9:58 AM MemberMouse integrates with Coinbase, which is an international digital wallet that allows you to accept Bitcoin currency on your site. There are 2 different types of Coinbase integrations, Wallet Required and Wallet Ignored. Coinbase (Wallet Required) works like a traditional card-not-on-file solution (much like PayPal) but customers can use Bitcoins to pay. Coinbase (Wallet Ignored) allows customers to purchase recurring products directly from any Bitcoin wallet without needing to have a Coinbase account/wallet. Payments will still be handled behind the scenes by Coinbase, and you, the merchant, will still receive payments into your Coinbase wallet, so you'll need to create a Coinbase API key and secret. Sign up for a Coinbase account at Once your account has been approved, you will need to complete your merchant profile, which can be found here. Next, you will need to set up an API Key. Click 'Settings' in the left hand menu from your Coinbase Dashboard: If you have not already created one, you will need a new API Key. After verifying your account access, you will see the screen below: Select 'Show' next to the API v1 permissions (legacy) link: Select/Set the following options in this screen: Accounts:'BTC Wallet (Primary)' -The primary account you are using on Coinbase. Permissions: Select orders, recurring payments, buttons, and merchant. Notifications:You can ignore this field. You will see the API Key has been created, but not enabled: Click Enable. You will have to verify your email address in order to enable the API: Once the API is enabled, it will look like this: Now click the API key link, and a popup will give you your API Key and Secret: Now, you will need to copy that API Key and API Secret to be used later How T Continue reading >>

Please Explain: Api Keys, Shared Secrets, Bitcoin Trading Software, And Bots

Please explain: API keys, shared secrets, bitcoin trading software, and bots OK so I know what an API is: "Application programming interface". And what i'm learning is an API key is a special password that allows programs access to your Bitcoin exchange wallet. What I need to know, is how secure this is. I understand that if someone has your API key this is basically the equivalent of your master private key to your wallet. With the API key someone they can steal your money. ( ) So I need to understand how to keep this secure before I go create one and put it into a strange trading app I just downloaded off the internet. And what is preventing a software program like From simply relaying that private key to a 3rd party (or software designers for that matter) and allowing them to steal your coins? ( I'm getting the notion that most people use trading software and bots to trade bitcoin, so i'm wanting to try this as well since i've not been profitable yet, and maybe this is the solution. ) In order to get the maximum amount of activity points possible, you just need to post once per day on average.

Bitcoin Price Drops 10% As Hackers Exploit Binances Api Keys

Bitcoin Price Drops 10% As Hackers Exploit Binances Api Keys

Welcome to another rollercoaster day for the cryptocurrency community. In just a few minutes, bitcoin price crashed from $10,740 to $9,690, which represents a 10.8 percent crash. As always, its a bit hard to know for sure whats happening. But one company in particular is having a bad day. Cryptocurrency exchange Binance has spotted some unusual activities and halted withdrawals. Binance is one of the biggest exchanges out there. According to CoinMarketCap , its one of the 4 biggest exchanges for the top cryptocurrencies when it comes to traded volume. Many people noticed something highly unusual with Viacoin happening right before the crash. There was a huge increase in buy orders for Viacoins on Binance. In just a few minutes, Viacoins market capitalization jumped from $64 million to $159 million Binance looked into it and noticed unauthorized sell orders. We are investigating reports of some users having issues with their funds. Our team is aware and investigating the issue as we speak, the company wrote on Reddit . As of this moment, the only confirmed victims have registered API keys (to use with trading bots or otherwise). There is no evidence of the Binance platform being compromised. So it seems like a third-party service or app got compromised. Users of that third-party app were relying on API keys to control Binance accounts. A hacker may have developed a bot that submits orders at the same time (7:00 AM Pacific). While the Binance team halted withdrawals, it might be too late. Its also possible that the hacker already had a big position in Viacoin on another exchange. The hacker could have sold a big pile of Viacoins shortly after manipulating the price on Binance. In all cases, it proves once again that security is a big issue when it comes to cryptocurrenci Continue reading >>

Block.io: Bitcoin Api And More

Block.io: Bitcoin Api And More

Block.io does not control your addresses, you do. You use the Blockchain to process your own assets. Processing a transaction on your website takes only a few steps: When a user owes you coins, create an address on Block.io for them by calling get_new_address. You can use a label to identify this transaction. For instance, get_new_address with label=useridXdonutsXdate. The get_new_address call will generate a new transaction address. Give them the new address so they can send you coins/assets. You can now check if the user has sent the transaction by calling get_address_balance for the above label. If the coin balance returned is the amount you requested from your user, you can give them their merchandize. Simple. When presenting the address to your user for the transaction, it is best to use a QR Code to make the process simpler for them. You can generate QR code using various libraries, including this one for Javascript. With Block.io, you can create wallet addresses for users inside your games, auction sites, stores, etc. To create a user's wallet on your account, create addresses for them using get_new_address. You should specify a sequence of labels for that user. For instance, if we wish to create a number of addresses for User A, we'd want to call get_new_address with label=userAx{address_number} as many times as wish to create a new address for User A. Once we have addresses for User A, we can query balances for their addresses, and send coins on the user's behalf. Our Green Addresses () allow our users to transact coins instantly with enabled sites. More specifically, we ensure coins cannot be double spent, so our users can use coins without network confirmations. This removes the Blockchain confirmation delay (10min for Bitcoin, 1min for Dogecoin, etc.), whil Continue reading >>

How Your Trading Api Keys Can Be Used To Drain Yourfunds

How Your Trading Api Keys Can Be Used To Drain Yourfunds

How your trading API keys can be used to drain yourfunds Many crypto investors have probably not given it enough thought. The exchanges have implicitly made us believe that as far as your API keys are disabled for withdrawal, it will be hard for anyone to move your funds. But recent hacks are beginning to make it clear that the new target of attackers is traders API keys. This especially goes for traders and investors that use bots and different cloud-based services to manage their accounts. Just 2 days ago, there was a widespread rumor that Binance may have been hacked . This was due to an attack on certain users accounts which used funds from their accounts to manipulate market prices. Binance has claimed this was due to improper handling of API keys by bots used by the affected users. Phishing attacks from last month which stole user login credentials may also be responsible. I doubt the attackers lost money as Binance claimed though. Not if they implemented the strategy below. How did this attack play out? Simple. The attackers got hold of users trading API keys. Since they are able to trade but not withdraw, they needed a way to manipulate the market. A common way to do this is via a pump and dump. In a typical pump and dump, a number of users would come together on a secret group and try to artificially increase the price of an asset by buying up a large volume of the asset over a very short period of time. This price increase will then trigger some other investors or bots to buy in and get on a potential bull run. The domino effect that results will further serve to increase the price. Usually, the organizers of this pump and dump group would have done a pre-pump by buying up the asset before notifying others of the chosen asset. Depending on the target of the p Continue reading >>
