On February 16, 2018, Coinbase admitted that some customers were overcharged in error for credit and debit purchases of cryptocurrencies. The problem was initiated when banks and card issuers changed the merchant category code (MCC) for cryptocurrency purchases earlier this month. This meant that cryptocurrency payments would now be processed as "cash advances", meaning that banks and credit card issuers could begin charging customers cash-advance fees for cryptocurrency purchases. Any customers who purchased cryptocurrency on their exchange between January 22 and February 11, 2018 could have been affected. At first, Visa blamed Coinbase, telling the Financial Times on February 16 that it had "not made any systems changes that would result in the duplicate transactions cardholders are reporting." However, the latest statement from Visa and Worldpay on the Coinbase blog clarifies: "This issue was not caused by Coinbase."[45]

Coinbase has two core products: a Global Digital Asset Exchange (GDAX) for trading a variety of digital assets on its professional asset trading platform, and a user-facing retail broker of Bitcoin, Bitcoin Cash, Ether, Ethereum Classic, and Litecoin for fiat currency.[24] It also offers an API for developers and merchants to build applications and accept payments in both digital currencies.

RippleNetはXRPを使用しています


Yes. Bitcoin has not been made illegal in any country to date, although some nations restrict its use more heavily than others. Bitcoin is often associated with crime, because it can be used to make criminal transactions. However, this is true of any currency. Bitcoin is harder for authorities to trace than digital fiat transfers, but easier to trace than cash, and most criminal transactions in the world are made with fiat, not Bitcoin.

Ripple positions itself as a complement to, rather than a competitor with, Bitcoin - the site has a page dedicated to Ripple for bitcoiners. Ripple is a distributed network which means transactions occur immediately across the network - and as it is peer to peer - the network is resilient to systemic risk. Ripples aren't mined - unlike bitcoin and its peers - but each transaction destroys a small amount of XRP which adds a deflationary measure into the system.

あなたは、暗号に税を払いますか


Coinbase has lost my money twice now. Once was due to an old account that, thanks to a bug in their verification process, I cannot re-authenticate. I bought 1 bitcoin back when they were only about $50 each with Coinbase. That money is gone forever now. And I acknowledge that it’s my fault that I did not set up a forwarding email with Coinbase, their support just refused to help. The second time was a month ago. I made a trade on Coinbase, and for some reason, the app glitched to think I have 5x more money than I actually… Read more »

Hey to all. Since around 2 months, I am with 99bitcoins reading and getting info and I am very happy here, thanks for a good site. For my bad luck I did not check here for a review of coinbase, I would have save a lot of worthless time. To tell the truth, I hope there is a internet god out there and shut them down. I did not know about their support in US, but as I read the first reviews here, it seems they make themselves a pretty bad place there too. I am located in the D.R.,… Read more »

Despite the intricate technology associated with and necessary for cryptocurrency investing, speculation and possession, Coinbase has created an apparatus that makes this process remarkably easy and familiar, almost like buying and selling stocks. This screenshot from the Coinbase site shows real-time cryptocurrency prices and doesn't look too different from your ordinary online stock tracker.

Preparations for the launch of Bitcoin (BTC) futures on Bakkt are on track. While market participants were excited before the launch of CME group’s futures trading at the end of 2017, the current launch is being approached with caution. Bitcoin’s volatility continues to drop, which shows that both bulls and bears are not taking large directional bets.

Essentially, if you are interested in trading in digital currencies but don't want to get bogged down in the underlying technology, products like Coinbase are a way to begin a foray into a new form of currency speculation and investing. You do, however, lose some of the advantages of trading in a cryptocurrency and through the blockchain. On Coinbase, you have no pseudo anonymity—your name is attached to your Coinbase account and so is your bank account, so transaction history is relatively easy to track down. And if you're not working on the blockchain, there's not much you can do to ensure that the verification of your transaction history or your account is taking place on the blockchain. You are, instead, placing trust in the intermediary, in this case, Coinbase.
