DO as I do with old hardware I still even using my usb asics. Just use them for when new coins come along mine them for a few days then stop using as diff spikes up on them. Mining days are over with the old 60GH units but still can be useful for a few days mining to get some new cryptos before hitting markets.
Yeah I agree with this. Do it for the fun of it and not exactly the profit. You never know one day the coin may be worth something.
Is what I did with zeta coin when it first come out mined about 12.5 million of them sold for about 6 to 7 btc held 1.2 million back sadly lost my key and wallet due to data loss and failed hard drive shame as when it keep they would of been worth close to 1300 BTC back in dec and towards mid 2013. So much has changed with zeta and seems it is dying out. No one active in irc any more and the thread is almost abandoned shame really as it had a really good wave of rise fall and constant stream.
