Bitfinex is an exchange currently based in Hong Kong, and has been operating since 2012. The platform has a very high volume of trading, being one of the largest in the market. My assessment of Bitfinex as a user is that at first, Exchange strives for security, as the user only has access to basic functions within the exchange after checking the 2FA, that is, it may be an excess since, by default, exchanges require 2FA as optional. Within the platform, its features seem a bit confusing, I don't particularly like its layout. Finally, I see Bitifinex as a reasonable option to trade crypto assets more for its volume of trading and countless trading pairs, but not for its usability which could be cleaner and more pleasant.
