Surprisingly, the waves do not fall, the people believe and buy? or is it the developers themselves artificially support it?
I think phishing or scam occurred when people bought into them. Think about why a coin can exist and not decrease in many coin drops. I think simply, waves are fake or in other words do not believe and buy waves if you do not want to be fooled
You are the type of person that called bitcoin a scam, and wish you didn't.
