yeah the credibility will get increased if they solve this issue as soon as possible. and the trust of the Trader will get increased as well by #SAFU, Binance only have a week to Maintance the system and security and reactivated withdrawal and deposit. if they can't afford it in a week, then the credibility and the trust will decreased.
I think 7000 BTC only accounts for 2% of Binance's total assets and we don't need to worry too much because Binance will come back soon. Binance will have many policies to support all their customers and people will still have great faith when participating in this exchange. Anyway this is a huge lesson that Binance needs to avoid and security enhancement is needed in this market
