Coinsbit is a well-known and popular exchange. This exchange is used every day by tens of thousands of people from all over the world, and you are talking about a few cases that you have mentioned for over a year.
Should I keep posting lists of scammed victims which issues are still not resolved?
Publish complete lists with detailed evidence and descriptions of all circumstances. I will pass this information on to Coinsbit security and they will check everything thoroughly. If there is an opportunity to solve something, then I think that the exchange will solve the problems of your acquaintances whom you call victims for some reason. Unless, of course, these are real facts and not fiction.
