Heh, gotta love that!
My best ROI story was canceling a KNC Neptune order. Paid ~11.5
BTC for it, and was refunded ~27.5
BTC.
Wow you made 16 BTC profit, that's the best ROI one can get lol
well congrats, but all depends on how much BTC is worth when you purchase and how much it's worth now when you get the refund.
