Если забыть про то, что лично я покупку биткойнов настоятельно не рекомендую,
то стоит ещё определиться насколько быстро вы хотите это сделать? Одно дело сделать
перевод 10 миллионов одним траншем, другое дело - в течение нескольких недель из
разных банков по-немногу.

Финансовый мониторинг обязательно поинтересуется переводом на 10 лямов. Так что если
бы мне нужно было такое провернуть - я бы делал маленькими суммами. И даже лучше
не через биржу, а в меняльных конторах. Список тут: http://www.bestchange.ru/

Никогда таким не занимался. Наоборот продавал бетховены за бабки.

You should download wallet which can open your backup, try to remember what kind of wallet you used previously since usually you can't open the file in different wallet application.

You're entering the command in your debug console, it should be run from the terminal

You're on a Mac, yes? If so, open up the Terminal app. Then type:

Once Bitcoin Core starts from this command, you should see that all of your unconfirmed transactions will be gone. The same behavior with those four transactions never happening should still happen.

This command will remove that transaction and the above three from your wallet, thus allowing you to resend the Bitcoin locked up in those transactions. It will be as if those four transaction had never even happened in the first place.

If you feel comfortable with invalidating these three transactions: https://blockchain.info/tx/c76068178d3e0cec7660cfea13b0326516707d7b2410e4987441026eb6662588, https://blockchain.info/tx/5506dd186fc7ef3f5b3cd24677927d77773b103397c8b747f94fad8a9255bf32, and https://blockchain.info/tx/4c6a6058ba14bff85323d50844ca52d4a25ffa72464555184568888f8480c7e2, then you can remove the one I linked to earlier from your wallet and be able to resend the Bitcoin from that transaction. If any of the above three transactions are also yours, then the coins sent by them will also reappear in your wallet.

The following will essentially revert your wallet to whatever it was like before any of the linked to transactions existed. Just go to Help > Debug Window and then the Console tab. In the box at the bottom, type

This command will remove that transaction and the above three from your wallet, thus allowing you to resend the Bitcoin locked up in those transactions. It will be as if those four transaction had never even happened in the first place.

As was mentioned in the other thread, your transaction is dependent on this transaction: https://blockchain.info/tx/152a65239eec41036614612be23f124f9ef861b30b521c57c9ff12c8c773b792 confirming. Is this transaction sent by you? If so, then there are solutions, otherwise, there is really nothing you can do.

That error means that the fee was too low or the transaction was unconfirmed for too long that blockchain.info decided to remove the transaction from their database. This does not mean that it was dropped from the network. Also, it appears that the transaction you mentioned in the other thread is still on the network.

It is part of a long chain of unconfirmed transactions, none of which can confirm until the first one does. Which it likely won't, since it pays no fee.

I think the problem is due to the way fees are calculated now due to network congestion. I'm not sure why the notice disappeared. I would recommend you backup your wallet, and upgrade to 0.12.1.

Just upgrade to Bitcoin Core 0.12.1. The upgrade will not mess with your wallet, and you will not need to redownload the blockchain. To be safe, you should backup the wallet file to a safe location. Just go to File > Backup Wallet and save the file to a safe place.
