For me better option are websites like
https://buycoinnow.com in contrary to exchanges because i don't need to register and input my data there, safety is a priority for me
That's for sure. I think that this kind of sites are also the quickest and the easiest method of buying BTC. You don't have to register, so it's quick and clear, all you need is your credit card
Yes, Buycoinnow is fine, but this is great option for the beginners, because if you are a trader you will have to transfer these coins on exchange
Well, that's right. If you want to trade you need to register on the cryptocurrency exchange, like for example
CoinDeal, I can recommend this one
