the only way failure modes I can see is if the exchange takes the money and runs, if there is a catastrophic failure of the trading engine, or if they get hacked.
The exchange can just fail in a large variety of ways and close (go bankrupt). If you’re not “insured” you are exposed to the trading risk and insurance costs what, about 30%? and, of course, it doesn’t help you with the exchange counterparty risk.
30% per annum? Even if this were true (and this sounds quite high, as I mentioned with Gwerns 1% per month estimate) then providing liquidity with them would still be +EV (86% increase vs 30% risk).
Ahh, oops. I think I missed the last line… I thought if someone exceeded their margin, they were forced to close their position so that no money was lost.

Um, did you make your post without actually reading the Bitfinex site about how it works..?
Upvoted for pointing out my stupid mistake (I assumed it works in a certain way, and skipped readig the vital bit)
