I agree with what OP has said.
Scammers will surely do thing that isn't easily to recognize their real intentions by investors. May the have a huge market offering but that was it looks suspicious and far from reality, and that it makes them change their tactics and even well-experienced investors never see it. It is obvious that they are smarter than us but of course, this kind of illegality will no longer stay for long.
Well, they are actually smart and will do everything they can for them to scam people, they will lie and as much as possible they will make you happy all the time and they will hype the price market because they know that you will be happy when you see the price is growing then when you already give your all in investment that's the time they will dump.
