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.
You should only consider reputed Bitcoin and Ethereum exchanges like Bitcoin Exchange, Trading BTC USD, BTC EUR - CEX.IO, Coinbase .
My personal favourite ,Bitcoin Exchange, Trading BTC USD, BTC EUR - CEX.IO is the best Destination to buy/sell Bitcoins,Ethereum and Litecoins. It is a Bitcoin exchange and former cloud mining provider, established in London, 2013. As an online digital currency exchanger, offers trading Bitcoins for fiat money, such as USD, EUR, GBP and RUB. They have a global reputation as a bitcoin exchange , and they offer high grade security.There are customer from all around the World.
All you need is to register on their portal and submit some documents , get verified. You are on ! You can use their pre-decided buying option or you can alternately create a custom price by entering amount of bitcoins and expected value. You can pay using your selected payment method , your card or your bank account.
