Thats for sure! Security is a very important factor for the development and popularity of exchange among users. If there is no proper level of security and people are not sure that their money is safe, then no one will use such an exchange. As far as I know, the COINSBIT exchange had no security issues. It is perfectly!
My friends use the project and there are no problems, they trade and everyone is happy
I heard that there are some complaints about the project, but i understand that apparently the person violated the rules of the exchange itself
