What if a bank closes your account for trading with Bitcoin? what will happen to your money and what will the cons of such thing happening (except for losing your bank account which could be seen as positive)
You don't need to exchange your Bitcoin directly to your bank account.
It's much better, in my opinion, use exchangers, so that your bank can't find out origin of your money.
I don't really agree with exchangers because of the history of most exchangers and most exchangers don't allow buying from the UK I'll be using localbitcoins bank transfer and hopefully meeting up locally eventually.
