Bitfinex is a scum exchange. I can't find one single reason why people still use it after everything they have gone through. It's like people don't even care anymore, which they eventually will pay the price for.
They've always gone on about liquidity and the UI. People always think exchanges will fuck everyone but them which is why they continue to use them. BFX has become slowly less dominant, a lot of big moves don't start there any more, and long may it continue.
There are no alternatives to exchanges right now so people have no choice but to take the risk of using an exchange platform for their trading activities. Until a real DEX platform arrives people will stick to this centralized custodial exchange for their money.
