So who is going to be requesting refunds?
If you do, please update us here on the status. I'm sure if a few people can successfully get a refund, the masses will follow.
Black Arrow, you should prepare your wallet and just refund customers with BTC no matter which way they paid you.
If you refund people and the X-2 isn't complete garbage, I'm sure people would buy a few. Also, when you drop the prices of the X-3 and X-1, a bunch of us will probably use the the refunded BTC to buy back the X3 and 1 at fair market prices. I would just because you acted in good faith for once and treated the people who funded you with a bit of respect.
