Payout less than 2% whenever he feels like it? I'm not too good at math, but I'm pretty sure I'll be dead before he repays at this rate.
Seeing how the MPBOR has been dancing between 5 and 10% a month since about forever it's quite clear you're never getting repaid in any meaningful sense of that word. You're just getting diluted into insignificance, which is kinda the plan with these "will pay you when I get to it" schemes.
Kludge, Hashking, whoever else all do the exact same thing. It's the one way that forum scammers have discovered to both avoid any serious service for their debts and avoid getting the tag: an unbacked pledge of good will and nice intentions.
Inasmuch as it works to redistribute BTC from the people with good intentions to the people with functioning brains it'd seem a net positive for BTC in general anyway.
Have any customers been given preferential treatment on repayments?
Seeing how things are commonly handled (take amazingrando as a fine example) even to the point that it's expected (see the Bitcoinica early drama), probably. How'd you know for sure either way?
Why can't held coins at least trade on bitfloor? Isn't he running an exchange?
Because that'd compound the problem (in effect creating a fractional reserve exchange, and a very very fractional one at that - they lost more than what they trade in months).
Why can't he offer incentives for holders of his debt to trade on his site?
Because he's bankrupt. And because he compounded his idiocy early on with the financial stupidity of not paying out right then and there, which has in effect turned his debt from ~300k usd to way over 1mn by now. People don't usually realize the importance of financial management, however here it is loud and clear: the loss from bad coding practices? 300k. The loss from poor financial management ? 700k+. More than twice. Same goes for
Asicminer and in general there's tons of examples around.
He was partying in London at the time, and didn't even bother to come back early
I don't do business with people who unilaterally seize my money. You shouldn't either.
There is this subset of idiots who go by feelers rather than facts. Blissfully they are decreasing in total BTC holdings even if increasing in numbers. They are the people who don't matter, basically. In due time their stubborn idiocy will have worked them into the exact corners they inhabit irl, and then we'll hear all about how the conspiracy of the rich is keeping them down. History repeats.
