It's akin to gambling. Many entrants tell themselves they'll only allocate as much money as they have to lose, or that they'll withdraw their initial investment after the first 100% gain. Sadly, they usually get overconfident when the scheme doesn't immediately collapse and end up investing far more than they would normally be willing to risk.
