What would you consider a pyramid scheme on this forum? A dodgy altcoin? a dodgy IPO? can you put some examples of demonstrated pyramid schemes that have happened in this forum?
I can't think of any right now. I just remember tons of dodgy altcoins and people buying into them, but you knew you were taking a big risk by doing so.
Umm... go look in the investor based games sub forum as it's a whole board dedicated to them, but yeah there's lots of ipos and alts that are pyramid scams along with cloud mining companies as well.
