A big thanks to all our users, also for the suggestions we get via email. We try our best to get them all covered.
Some of the API code was improved and rewritten, such that the requests are processed without delay.

We've also noticed a rapid increase in the number of mixes during the past month. That's why we added some further server infrastructure, to keep the mixing as fast as possible.

Have a good mix

Well, coinbase owns the private keys and won't reveal them to you. So, it's basically their decision if they allow you to spend any kind of forked coins.
If you are worried about future forks and want to be able to spend your coins on any branch, then make sure to own the private keys to the addresses where your coins are deposited.
You can use Bitcoin Core for this, as an example.


Either coinbase doesn't care and leaves them wherever they are, or they use them on their own.


Simply by sending it out of your wallet to a coinbase-owned address. Depends on the wallet that you use.

What do you mean by "the wallet"? There are dozens of wallets out there. Do you already use a specific wallet?
If you want to control your funds and want to know that your funds are located at your own computer, which is what I read from your question, you could use Bitcoin Core as a wallet.

Just generate an address there and send your funds from coinbase to this address. Then, you are in perfect control of your funds.

As long as you don't give away any private keys, yes.
Just be aware that they can then see all transactions going from and to this address.

It's best to generate a new address for every service you use and transaction you do.

But let me just ask you: why do the websites want it? Do you get payed something out?

Wait a bit. It might take some while.

Next to the links mentioned above, you might also check out the youtube video, which Bitcoin Tutorials posted several months ago:

Sure.
Just a tip for your privacy: Create a different receive address for each received payment. In your image "Goingbig" was just used multiple times for receiving funds.

Your fee is 40 sat/byte, which is too low for most accelerators.
There will be times when there are fewer transactions pending, then your tx will get confirmed. Many mining pools also prioritize older transactions, so be patient...

Probably yes. What you can do is Settings->Wallet->Enable Coin Control, restart core, then you can specify exactly which coins should be used when doing a transaction. Just tick the addresses at which your new money arrived.

And you can check your transaction at the link above, as soon as it doesn't exist anymore, it's time for a resend.

But I guess that it will eventually get accepted, without resending it.

You don't need to cancel your last try because it wasn't even accepted by the network at all.
Just remove it out of Bitcoin Core with zapwallettx or similar.
No, you can't 'cancel' transactions once they are broadcasted, the only thing that works is waiting until they're removed from the mempools of the majority of nodes in the network.

Just look here, your old transaction is still pending:

Yes, but it has to be activated via commandline (don't know if it is default on already, in 0.14 it was default off...)

Yeah, because your old transaction is still pending and not removed from the mempool.
A few days later it should be possible.

It's all right, you did NOT lose anything.

Your transaction is still in the mempool. Other peers of the network still know about your previous transaction.
So, either it confirms within the next few days and thereby it arrives at your destination address, or it gets 'forgotten' from the mempool.

Wait a few days and rebroadcast it again if it does not appear at the destination.

You could also enable the "Replace By Fee" option next time, to be able to rebroadcast it directly.

Actually, if your computer is infected, there is not much a wallet itself can do to solve it. The malware could hide on the system driver level, so the application in user space has no chance to detect it. If there are wallets that claim to be able to cope with it, it sounds suspicious to me.
The risk itself is quite serious, as there are many versions of malware around that are crypted by non widely known algorithms and by that they bypass a lot of AV scanners.
Problem is that a lot of this malware has special functionality to detect if a cryptocurrency wallet is installed and it filters the data to only capture this part.

In general, linux operating systems are not targeted that often. For high-volume transfer handling, I generally recommend using a dedicated machine that is set up from scratch, where only required software gets installed. Then, you can setup a firewall to only allow a specific process to communicate out of your machine. This should give you maximum security.

Better safe than sorry...

Where did you download your version? Was it a precompiled binary or did you compile it from sources?
If it's not an official build, there might be errors in the specified .h file.

There may be more services, but many of them require high payments without a solid guarantee for acceleration.
As the miners do not get a lot of revenue from your transaction (as its fee is probably very low), they charge you extra for it.

Yes, it is normal that sync with the blockchain takes some time. The core downloads the blockchain and checks it, this takes time.
Your funds will arrive, you even if your wallet is out of sync. It will appear as soon as the sync is completed

You can check the tx on blockchain.info by entering the tx id.

Next time, use a somewhat higher fee and it will go through quicker...
