Hello, what is best exchange site where I can buy Bitcoin for fiat via bank transfer? And how long it needs to show that this money is on my balance?
Some exchanges need 5 days and that's too much.
Binance, Bitrex, Kucoin, coinbase
Maybe I'm missing the point here, but AFAIC the question was "for FIAT".
Binance & KuCoin does NOT allow to buy for FIATs.
Coinbase, Kraken, Bittrex (?!), GDAX does.
