BTC-e
And why?
They don't ask for ID. Super simple registration.
True, but my funds get delayed. And support sucks at responding..
I always have to buy like a btc-e code from someone.
BTC-e is always the first choice. You can try bitstamp and also kraken is good, so i have heard now. poloniex is also pretty reliable as is bittrex because of the user-friendly interface. Newbies should start with bittrex i think.
