There is an alternative. So I'm sure you guys know there are a ton of die hard Electroneum fans out there (me being one of them) and they used to mine ETN back before it became ASIC friendly (me being one of them).
I bought a mining rig from a coworker for fairly cheap and bad timing, right after that they (the ETN DEV team) switched the blockchain back to ASIC friendly.

So one of use came up with a pool that mines other cryptonight coins that can still be profitably mined and sells it on an exchange and pays you out in ETN. He switches coins to keep the profitability up. Right now the focus is around cryptonight fast coins.

So you could do this with other coins and algo's and still keep your GPU's mining. You just need someone to start a pool like that for your preferred algos and coins.
