There was a computer parts company that had an accidentally very good deal on a part. I ordered one using BTC through coinbase. Eventually the company realized their mistake and canceled everyone's orders. I got refunded through coinbase and forgot about it. Turns out the company forgot about it too because several years later I get a letter from them saying "our records show we still owe you this refund, here's a check". I'd say my money got doubled but that would not be true. When I ordered the part was within a day or so of a major BTC downturn and by the time the BTC came back through coinbase it had devalued substantially. Buying the part was my attempt at getting out while the market was high. Still, ended up ahead in the end.
