And regarding markets for buying BTC using fiat.
Which are the less bureaucratic, most reliable and fastest sites for doing that, for Europeans?
By fastest I mean I don't have to wait hours for the buy to happen nor for the transfer between wallets. And my email and CC are enough.
Is there any thread here or site that reviews/classifies trading sites? I don't want to trade with some other "mt. gox".
Thanks
Fastest in Europe is localbitcoins.com with your criteria. I would sell you some, but I'd have to sell some DRK first and that's against my religion.
There are several ATMs if you are in central london. There is also a random guy in Brick Lane somewhere that has a bitcoin shop. I think its a pop-up shop, so might not be there for much longer.
