No, you were not defrauded because you did not lose anything real. You did not lose 10 BTC. You did not lose $1,556.76. You lost potential, yet unrealized gain as a result of the delay in processing your order. You may have not had access to either amount for a period of time because of the flag thrown on your transaction. AFAIK, Coinbase does not publish ...

I actually had this same issue today. You can find your BTC deposit addresses on coinbase.com under... Account Settings / Integrations tab / Bitcoin Addresses (scroll to bottom) Here you can add new addresses as well as "view all" I hope this helps! :)

Coinbase is built on top of Bitstamp. They may work with other exchanges now, but they are (and used to be) very tightly coupled with Bitstamp. There was an exploit where someone discovered that Coinbase's price was set to the last sale price on Bitstamp. Basically, this person would sell a small amount of Bitcoin for much lower than market value on ...

The last stats Bitpay published were in December, 2014, so it may be somewhat out of date. They said that 10% of the merchants keep settle entirely in Bitcoin, 41% of the merchants keep a part of their settlement in Bitcoin, and the remainder settle entirely in fiat. That said, there are plenty of instances where BitPay merchants get settled in Bitcoin, and ...

Basically, yes. Coinbase is notorious for this type of shady practice; hit me just last week. At least you got a reply, their customer service ignored my requests for updates. A few quick searches will find you quite a few repeats of this same old story. It's best to not think of Coinbase as an exchange at all; think of them as just a store that sells ...

For every Bitcoin they sell, someone else had to obtain that Bitcoin. So they increase the demand for Bitcoins by at least as much as they increase the supply. In addition, they increase the utility of Bitcoins, which increases their value. All other things being equal, a currency you can spend at more merchants is more desirable than one you can spend at ...

In a limit order, you specify how much of the asset (in this case BTC) you want to buy or sell, and the price you want. If there are matching orders on the book (e.g. someone who wants to sell at the same price, or lower, as the price at which you want to buy), your order will be filled immediately. If not, your order will stay on the book until matching ...

If you didn't move out your BTC before the fork, then your BitCoin Cash tokens remain with CoinBase. They are not really lost, but they might remain in their system for a while. Here is the explanation directly from CoinBase Support: We are planning to have support for bitcoin cash by January 1, 2018, assuming no additional risks emerge during that time. ...

Coinbase no longer supports any sort of wallet import (wonder why?). To quote Coinbase (June 2016 on https://support.coinbase.com/customer/en/portal/articles/2285419-how-do-i-import-an-existing-wallet-) Coinbase wallets currently do not support a wallet import feature. If you have paper wallets, private keys, wallet.dat files, or brain wallets, they can ...

I'm with Coinbase (proof), better late than never with this answer. We do have a way of doing this now, though it requires some extra verification steps to properly link your account to the business entity. Email us at support@coinbase.com

Yes! With an HD (Hierarchical Deterministic) wallet you control all the addresses inside of it. Using a new address for each transaction is actually a good thing for privacy. https://en.bitcoin.it/wiki/Deterministic_wallet https://community.coinbase.com/t/why-did-my-address-change-did-i-lose-some-payments/1589/2 To answer your last question you don't need ...

At the time of the question being posted, Coinbase was paying your transfer fees. Starting on March 21st 2017, they stopped paying the transfer fee and the user now pays the fee. Coinbase has blog post about it here: https://blog.coinbase.com/coinbase-spring-cleaning-4f27710ff821#.b8hzpa2hb

This is normal. You can see on https://bitcoinfees.earn.com/ that BTC 0.001 is a pretty average fee right now. You should not think of it as a percentage, since the fee for a transaction is not related to the amount of coins transacted. Instead, it has to do with the size of the transaction in bytes, which is more a matter of its complexity (e.g. number ...

It's most likely that Coinbase keeps a reasonable reserve of both dollars and BTC on hand, to instantly provide either USD or BTC to clients. They probably have a "treasury manager" on staff, whose job is to buy BTC at the lowest possible prices and sell BTC at the highest possible prices on various exchanges or dark pools, to keep the reserves topped up ...

You can easily send your bitcoins from Coinbase to Electrum. Once logged into Coinbase click on the Send / Request button on your left hand menu. A form will pop up asking for an email address or bitcoin address. What you want to do is enter in one of your bitcoin addresses from Electrum. Open up Electrum and click on the tab labeled "Receive". You can ...

I did some digging into Coinbase's offline multisig tool to figure out what the user seed actually was and their derivation paths. It turns out the user seed is just that, a seed that is used to get the Master Private Key. This is done by hashing it with HMAC-SHA512 where the key is the string Bitcoin seed and the data is the binary form of the user seed (...

There are a number of reasons why this kind of blacklisting is problematic in practice, but take it with a grain of salt, because I'm the creator of Wasabi, so I am biased. This Elliptic report identifies 0.65% of all Bitcoin transactions are mixing transactions. This means, if that kind of blacklisting would happen, they would have to blacklist most ...

A transaction could go unconfirmed indefinitely. The order in which transactions are confirmed is decided by miners, and generally they will be incentivized to include only the highest fee-rate transactions, to maximize their revenue. Even a low fee-rate transaction may eventually confirm, once the mempool clears out. But there is no guarantee of this, ...

Brian from Coinbase here. Sorry you experienced delays! There have been some issues in the past that we are working to improve. Coinbase sends a high volume of bitcoin transactions (often in parallel across many machines), and as a result we sometimes encounters issues that are uncommon elsewhere. In this case, I believe the root of the issue was around ...

Coinbase did not defraud you. I've done over 500 transactions with Coinbase since July 2013. They are a legitimate Venture Capital funded startup. They do however make mistakes / have bugs in their software. However they always straighten everything out after I submit support tickets. Once they made a mistake that I submitted a support ticket about ...

If you're mining in a pool, bitcoind doesn't even have anything to do with the system. It doesn't need to be running, it doesn't even need to exist on your hard drive. The remote pool does that for you.

Unless you happen to know who owns 16fYQiV2cdHuycGo3eibE5JSKvndY2z8Gw, there is no way for you to get back your Bitcoin. You could try to raise awareness that this address holds stolen coin, but I don't see how that would benefit you in any way. What happened is essentially the Bitcoin equivalent of somebody taking your dollar bills from your wallet without ...

Yes, you can and should transfer your bitcoin to a wallet you control after purchasing them from a web-based wallet. Never leave a substantial amount of your bitcoin on an exchange or a web wallet. Coinbase is a company that runs both an bitcoin wallet service and an exchange for purchasing and selling bitcoin for USD. Armory is a wallet that you run ...

Since there is no dispute about the address, you can check whether the transaction has confirmed on any of the blockchain explorers freely available, such as blockexplorer.com or the aforementioned blockchain.info. If the transaction shows up as confirmed there, and the receiving address matches the address that he told you, the money has been successfully ...

When sending Bitcoin from Coinbase.com to an email address, you are sending the Bitcoin to another Coinbase.com account linked to that email address. So for example, if you had a friend who has a Coinbase.com account and you wanted to send them Bitcoin, you could ask them for their Coinbase.com email address and then send the Bitcoin to that email address, ...

Assessment I think you are slightly misunderstanding some things, but basically you are already on the right path. Wallet I signed up for a bitcoin wallet (coinbase) where I am given an id. Great. When you want to manage your wallet (send and receive Bitcoin, create new wallets etc.) on your local machine, that’s a must. On a side-note: in ...

Surely you were screwed. Before buying something from the internet, it is a good idea to look how legitimate is the source. Just a quick search on the internet is showing that a lot of people have these problems. If it would be really something with fraud prevention, they could have cancelled the money right away and you will receive them back in one day (...
