Asset issuers: Check.
Actually for some asset issuers this may be a lucky strike: they got money and probably will not have to pay back nuthin.
So much luck that someone rightly suspects that some of them may be co-conspirators.
Hm, well there is that.
However, if the issuer's plans in any way hinged on the continuing liquidity of their offered shares (as pretty much any honest plan would), they're still screwed in that regard.
Free coins are nice, though they can't (honestly) feel too good about how they came to possess them.
They will also surely have to deal with victimized users asking for their coins back, or shares, and will have no way to verify any claim.
Really it sounds like the only ones to truly benefit are any who were not on-the-level in the first place.
