Show them constructive criticism instead of shitting on them and maybe they'll hear you out and improve! Really they just need to automate 99% of withdraw/deposits and it'd be an awesome exchange!
Sorry, but if you in current times can't provide a properly working exchange, then you are incompetent and shouldn't be allowed to run or operate anything. As exchange you are dealing with people's digital assets, and that alone involves a tremendous amount of responsibility. If you till today are processing withdrawals manually, it clearly shows that you as operator don't actually trust your platform.
Another factor that
may play an important role here, is that the exchange itself is insolvent. If you delay deposits and withdrawals, behind the scenes you as exchange wait for enough deposits to accumulate, to then allow someone else to withdraw that specific coin. It can be seen as a scheme structure where the next investor pays for the previous investor's cashouts. Seriously, what do people actually know about this exchange?
People should just avoid these exchanges. If you do enough research beforhand, you won't have to deal with the exchange's incompetence afterwards.
