I've been scammed but not in crypto; it wasn't very much different though. And yeah many scammers regularly contact me, especially through telegram. Their methods are pretty simple, you just need to be careful.
If you have tried to join in a new project(i meant telegram group) and then you would have gotten a guy that will send a pm to your contact that offers you a very cheap coin with a lot of discounts and that kind of scammer in these days.
