I don’t agree but I respect your opinion because obviously you had bad experience. I didn’t have any problem with COSS.

How long have you been in COSS?

I have bought at 0.52$ two months ago.

Then you definitely missed the bad time. I suggest you check into it a bit before going in too deep. Hopefully it is in the past, but in my experience: a team that has made big mistakes before will make them again.
