I've often asked for help in the chat to complete KYC, and was once in a telegram group and said that more than 3 months the application is still "in process" then they block my telegram account.
If they even have the audacity to block you from the chat just for inquiring about your KYC status, then that speaks volumes about them being a scam exchange.
I have warned some members a number of times against using coinsbit because of the numerous complaints customers have against them. This should be a lesson that next time you first carry out due diligence before using a service.
