I normally hate the altcoin world but my old miner just isn't worth much on the bitcoin network. What might I mine that has a reasonable trade in value for bitcoin. Ideally I can use poloniex to trade or some other respected exchange. I don't want to hodl the altcoin, just mine it and sell.
The problem is that there is so much available hashrate that the profitablity of SHA256 coins hardly goes over that of
BTC.
I have a batch of obsolete miners that I've been keeping ready for a nice run on an altcoin but problem is that unless you mine and hold and hope for an upgoing trend of the coin there's not much money to be made.
