Yes

Actually, sweeping is recommended since when you export the private keys, you are at more risk of them being stolen. Sweeping makes sure that even if someone steals your private keys, there won't be any Bitcoin for them to steal. It won't work if you are offline.

It would, but it is a lot more work than necessary.

Now I know that you don't want to put the qt-wallet online again, but that may actually be the only way to get the funds from your qt wallet to armory. The problem is that bitcoin core uses compressed keys now and armory only supports uncompressed keys, so the keys from Bitcoin core won't be able to be swept or imported.

Go to the Accounts tab and in the upper right hand corner, there should be a button with a key and a plus sign. Tap that and scroll down to the bottom of the window that opens. Hit the button for Advanced. From there you can scan the key (were you using another scanner before? That probably wouldn't have worked, but the one in the app will) or you can import it from the clipboard. If the button for import from clipboard is grayed out, that means you copied it incorrectly.

You can just type the private key somewhere, select it and copy the entire string, then go to mycelium and import it from the clipboard.

Bitcoin is not anonymous, it is pseudonymous. This forum is the same, and if you have made it possible to link your forum pseudonym to your real identity, then that is your own fault. When people dox each other, they are using publicly available information, you would be able to find the exact same information if you actually spent time to look for it.

The payment request contains all of the necessary data for a transaction, e.g. the receiving address and the amount to send. The client parses all of that information and creates a normal transaction and sends the Bitcoin. It basically removes the step of giving people addresses to correctly copy and send to. You can read more about it here: https://github.com/bitcoin/bips/blob/master/bip-0070.mediawiki

Try doing shift+right click on the icon in the taskbar. Then select move and just click somewhere on the screen. If you can't click the move option, then click on the desktop and make sure that no window is currently selected.

They are getting nuked immediately by a bot. No one is manually deleting them.

There is nothing that can be done about it. You can't "fix ban evasion" for this since the guy posting is probably a bot which is using a proxy and constantly changing its ip address. There is nothing other than the account's first post that indicates that it is ban evading. You literally cannot ban them for ban evading if they haven't posted anything yet.

If you say that this can be fixed, then please, tell us.

Well I think the payment requests can already do what you describe.

You create a payment request and upload the request file to your site. If someone wants to pay, then they download that request and their client immediately recognizes it as a payment request. It will know where to send the Bitcoin and how much to send, so all the user does is enter their wallet password and hit ok. Then the client just sends the Bitcoin normally.

There isn't any way to send or receive Bitcoins without using addresses, but if you use BIP70 Payment Requests, then you won't need to give anyone an address. The address will be part of the payment request and most modern clients will do all the work for you. You just need to allow the send.

There is, kind of. You need to use the debug console. In the debug console, you can get information about a block using

where <hash> is the hash of the block.
You can get the hash by using
where <height> is the block height.

You can also get transaction info by using
Where <txid> is the txid. This won't always work since Bitcoin Core doesn't index all of the transactions by default. If you want to be able to search every single transaction in the blockchain, then you will need to enable txindex by adding
to your bitcoin.conf file or add -txindex to the command that starts up Bitcoin Core.

I highly suspect that you have been scammed since both the original silk road and silk road 2 have been shutdown. See this: https://www.deepdotweb.com/marketplace-directory/listing/silk-road-3/ for some info.

I have a little bit of experience with stuff on the deep web, but I haven't actually bought anything. I do know how those markets typically work though.

That should be fine then. As long as you sent the Bitcoin to the correct address, then you are fine, and you should contact the darknet site's support since then it is a service problem. It is ok if you did not click any button like "request payment" since those are not necessary for sending Bitcoin.

Why are you buying bitcoin from the darknet? Bitcoin isn't illegal, and if you want Bitcoin, that is one of the riskiest ways to do it.

If you sent the bitcoin to the wrong address, there is absolutely nothing you can do to get it back. If you know who owns that address, then you need to contact that person and ask him to return the Bitcoin. Since you are dealing with the darknet, the chances of getting anything back is pretty low. If you are sure that you sent the Bitcoin to the right place but they aren't crediting it to your account, then it is a service problem and you should contact support. Another thing, be careful on the darknet as many sites are phishing sites, so it is possible that you have been phished.

How is mining a scam? Mining is the method by which transactions are included in blocks to prevent them from being double spent. Mining is an integral part of Bitcoin, without it, Bitcoin wouldn't work.

Cloud mining is different, and most of the time cloud mining doesn't actually mine, they are usually just ponzi or pyramid schemes.

That and the site already tells you where they have posted and how many times they posted in each section.

I will add that. There will be an additional positive multiplier (e.g. price*0.7) for those sections. Can you suggest me some multipliers to use?

Those details should be in the bitcoin.conf file.

Although this is primarily an english forum, I don't think posting in other languages should have an effect on the price. However posting in off topic, and politics (and maybe altcoins) will have a multiplier at some point in the future.

edit: I may be able to have it tell you what languages the account has posted in, but that won't effect the price of the account.

Pretty much. The difficulty on the testnet is much lower than the mainnet, and it resets back to the minimum if no block was found in some time. I think a couple months ago someone was mining tons of testnet blocks trying to push it to go past the second halving for some reason.

No, I never said that. How do those articles lead to your conclusion? Please explain how I those contradict me (if in fact they do, then I probably missed something or you misunderstood something) and how those lead to the conclusion that the 7tps limit is irrelevant.
