Cex.io is one of the best and becomes my favourite platform to buy Bitcoins whenever I want to. I experienced very fast fiat deposit process into my Cex.io account using my Visa card as well as a very fast withdrawal process to get my Bitcoins into my other exchanger wallet. I give Cex.io 5/5 rating score because this platform is trustworthy and very reliable overall. Please keep up with this excellent standard of cheers!!!
