Not many users are believe Bitfinex, but you can mark my words if most users are leaving their coins on Binance since CZ offer SAFU and something that would make people think Binance is the most safest place. I'd say a real Bitcoin enthusiast or experienced people that came from this forum are only tiny portion of the whole Bitcoin market, that's why when a bad thing happen, Bitcoin price usually move on the hype news.

If Binance is collapsing and there's currently no popular exchange like Binance, Bitcoin price will crash since people think there's no place is safe.
