Bitfinex

Bitfinex is a crypto exchange built for people who already know their way around trading screens. By our assessment, it stands out more for depth than for friendliness: the main appeal is a wide market offering and the sort of tools active traders expect. The downside is that this kind of venue asks for attention and some comfort with order books, fees, and account security, so it can feel heavy if all you want is a simple buy-and-send flow. In practice, Bitfinex is the sort of place where the interface matters less than the market structure behind it. It sits closer to advanced exchanges than to beginner apps, and the learning curve is part of the deal.
