What kind of BS is that, why would crazyivan be responsible for my own investments?
If his non stop promotion of this ponzi is considered substantial assistance, he would be as liable as the perpetrators of this scam:
(b) Prosecution of persons who aid and abet violations
For purposes of any action brought by the Commission under subparagraph (b) or (d) of section 77t of this title, any person that knowingly or recklessly provides substantial assistance to another person in violation of a provision of this subchapter, or of any rule or regulation issued under this subchapter, shall be deemed to be in violation of such provision to the same extent as the person to whom such assistance is provided.

If by "bitcoin investors" you mean people who waste their precious bitcoins on scams and mathematically certain loss generating "investments", then all evidence suggests they are indeed unbelievably gullible.
