He asked a specific question and didn't look for a lecture. Whatever someone does with their money is their business, not yours.
You are absolutely right. And if you reread my "lecture," and check my posting history, you'll see I have rarely, if ever, stated that anyone should not deal with anyone. Pointing out evident corruption, or the probability of total loss, is different than falsely assuming the right to invoke
en loco parentis.
On the other hand, the taste in my mouth that comes from a quite general willingness among bitcoin miners to deal with devils if they offer a possibility of hashing hardware is one of the reasons I'm still around here
only to see the (hopefully) successful implementation of BFL's bare chips on DIY enablements.
Cheers.
