There's no way to "cancel" a Bitcoin transaction once it's been pushed to the network. It's true that occasionally, a transaction that remains unconfirmed with low fees will eventually fall out of the mempool and "disappear" but there is no way to force this to happen. You just need to wait for your transaction to confirm.

It's taking a while right now because some miners have temporarily switched from mining Bitcoin to mining another coin. Because it will be more profitable for them to mine Bitcoin in approximately 30 hours (from my post), that is when the large backlog of transactions will start to clear out and you should get your coins.

However, since your transaction is marked "replaceable", this means it was likely sent with RBF (Replace By Fee) which allows you to raise the fee of a transaction retroactively after you've sent it, before it's confirmed (which is the situation you're in now). If you really, really don't want to wait, you should be able to select the transaction (probably right clicking it in your transaction history in your wallet) and choose whatever option sounds like "raise fee" or "bump fee". Double check how much of a fee it's going to add before you send it though, because the network is very congested right now and you could easily end up spending much more than you wanted to on a fee.

My advice is to just be patient and wait about 48 hours to see if it will clear first.

It's probably a change address used by the wallet. Change addresses are what allows you to not only spend large chunks of Bitcoin at once. Unless your balance has decreased more than you expected it, you should be fine.

That API you linked to seems to be 4 years old. It could be a good exercise in learning how to scrape webpages if you want to try it. I would suggest using whatever server side flavor of jQuery is available in your language.

Hello,

Could you provide us with transaction IDs of those transactions? The exchange should list them under account history, withdraws or something similar

I'll consider changing it, this was more a first step to connecting AM to my local full node and using the JSON RPC to get data. I should be able to move the !last command over to this method now and reduce AM's dependency on third party APIs

I've added a command to AM to report Bitcoin Core's estimated fee on transactions. Use it like !fee [numblocks]

For example, to see what fee you should use for confirmation within the hour:

You should have read the two stickies at the top of this forum that mention stuck transactions, here and here. That said, your transaction seems to be confirmed now.

Electrum will create a new seed for you if you do not have one. This seed is used to generate many BTC addresses (As many as you need, there is no limit). All of the keys for the bitcoin addresses it generates come from this seed. And that is correct, as long as you have that seed stored somewhere, you can use it to re-generate all the Bitcoin addresses you've used in your wallet to re-create it and have control over your money. If Electrum disappears it would still be possible to use that seed and restore your wallet.

The private keys in this case are all derived from the seed, in what's called a Hierarchical Deterministic wallet (HD wallet). Those keys themselves are not usually stored, just the seed used to create them, because as long as you have the same seed you can re-create all of the same addresses. Bitcoins are never really "in" any computer or device, in the sense that if that device is broken/lost the Bitcoins are destroyed. The Bitcoins reside in the network, and the keys that are used to spend them are on the devices. If the device that has the only copy of the key to your Bitcoins is destroyed, those Bitcoins are lost in the sense that nobody can spend them. But if you have your seed written down somewhere else, you can use it to re-create your keys and regain access to those Bitcoins.

The USB devices (hardware wallets) use the same method as Electrum in that they use a seed to create addresses. As long as you have the seed stored somewhere safe, even if you lose the hardware wallet or it stops working, you still have access to your coins.

Bitcoin Addresses look like this: 1KsFhYKLs8qb1GHqrPxHoywNQpet2CtP9t. These are the things that you give to other people so they can send you money. Each bitcoin address is created from one private key, and each private key creates only one bitcoin address. The seeds used in modern wallets can create any number of private keys, so you can create any number of Bitcoin addresses.

It can be weird to think about how Bitcoin works for people just finding out about it. These hardware devices hold the keys you use to spend your Bitcoin. As long as you have these keys, you can tell the network to send your Bitcoins from your wallet to another. It is true that if you lose the device, you still have access to your coins, but this is only if you've backed up your wallet. Backing up your wallet is like making a copy of the key you use to send your coins, and putting it somewhere safe. Since this copy is usually on paper, it's not vulnerable to any sort of hack and can be safely stored in a fire safe, safe deposit box, under your pillow, etc.

You use your device to send your Bitcoins because that's where the keys are. In short, what happens is you use an online app that generates a "lock" for you (in technical terms this is an unsigned transaction). It then sends it to the device to unlock it (signing the transaction). Because your key never touches your computer, which could be infected with malware, it is much safer than a software wallet (a program on your computer instead of a hardware device).

The problem with Bitcoin is it is inherently a very technical system and can be hard to understand, but if you didn't get any of what I said just ask and I'll try to help you understand it.

Now, I don't really know how Ripple works, but there's a Ripple transaction here that seems to have been validated here http://www.ripplecharts.cn/#/transactions/EAAA38804C5FD50D31C68680F3DC4BD3CFD6A37FCE2A866307D33CA1938B0024

If the BTC hasn't been sent to the BTC network by however Ripple works, I'm afraid someone else will have to answer that one.

This belongs in the Investor-based games subforum, not the main one. This is a HYIP and people shouldn't be tricked into "investing" into a scheme.

That seems like a lot for fees. Are you using a different unit, like mBTC? And yes, if it is really in your wallet you can still use it to receive money. I would keep it in your old wallet if I were you, just in case.

I wish I could help, but I've been having issues with them now ever since they "upgraded" their new GUI. Almost never works for me, and I've tried a lot. If I were you I'd just mine the profitable coins directly on other pools with other miners.

I can't even sell my hashpower anymore because their "new" client is buggy and never works. I've gone back to mining the coins directly.

That's good advice, and you should keep following it. You should sweep funds when you want the money that's in the address. However, if it's the address itself you need, then you'll have to import it directly into the wallet.

If you're getting fees, you're not importing the vanity address, you're sweeping the funds into your own wallet, which creates a transaction. If you want to be able to use the vanity address you'll have to find a way to import the private key directly into the wallet

It appears you need to use the command line flag (can also be used in a bitcoin.conf file, read the linked article).

There are many advantages to using an HD wallet. The main one being a wallet backup lasts the life of the wallet, but without an HD wallet the backup only covers the addresses in use at the time of the backup. Additionally, wallet.dat files can get pretty big if you've got a lot of addresses.

Your best bet would just be to read guides on SEO (Search engine optimization). There are certain things you can add to your website to get it ranked higher. I believe with Google there are also things like mobile versions of the website taken into account, but I am by no means an SEO expert.

Unfortunately not. It is not any easier to derive a password from an encrypted and unencrypted version of a file than it is to find the unencrypted version of an encrypted file. Also, since the files aren't even the same file (one includes more private keys) it wouldn't be possible anyways.

What wallet are you using? If you're using a wallet that generates addresses deterministically, then it could be possible to generate the addresses you don't have in your unencrypted backup.

Bustabit is provably fair. There is no way they could have possibly cheated you. It would benefit you to learn the basics of how provable fairness works so you can gain a little peace of mind.
