I'm still trying to figure out in all of this what the Garza clans exit plan was. I mean surely they had some kind of this is how it'll all dissolve and end and we keep the money but get no repercussions from it. Did they not have an exit strategy or did the one they have just really backfire?
He was successfully making shit up for months and had a lot of loyal followers. I think it's quite likely that he believed in his own invincibility and in the endless supply of fresh money. His decision to launch Paycoin despite realizing the impossibility of the floor shows the kind of mindset they were in.
He also probably didn't think it would get as big as it did. None of what he said made any sense, and people kept giving him money. He shouldn't have gotten as much money as he did, and once the amounts got so high, it probably shifted into that invincible stuff. They believed he would sell them $20 bills for 4, why wouldn't the believe anything else he said?
