I agree because I notice a much more quiet events of scams in the last year up to the present compared to 2017. Scams like thebillioncoin, one coin that existed on facebook. There are also hyips that got me attracted and lost my money. Only left by now are those telegram scammers pretending to be part of any team. I don't see much of them nowadays but like you said OP, I'm certain that they are going to change their scam strategy.
