you may as well let them run away with your money.
I would really love to have the data HF has about the % of people who agreed to a USD refund and the % that actually sent a certified letter demanding a proper refund.
I would love to know the % of refunders who paid with usd vs btc. My guess is so far it as predominantly been usd-ers. I can't see any btc-ers willing to take a 90% haircut for HF.
