"Hey guys, just had one of those days - I was trying to mine some test BTC on an old rig and it looks like I mined a bunch of worthless Sats instead of the regular stuff. I've got a wallet with 37 million of these 'worthless' Satoshis now, which is pretty wild. Anyone know if there's a way to exchange these for actual BTC or do I just get to add some 'sentimental value' to my worthless coins?"
