If NiceHash isn't working - I think I could point to the MiningPoolHub equihash autoswitching port (17023), set my autoexchange preference to BTC... and end up with the same thing? It should mine the most profitable equihash coin MPH supports (ZCL/BTG/ZEC/ZEN) and keep slowly converting it to Bitcoin?
The only hitch for this plan (same plan I have btw) is that MPH uses bittrex to auto-exchange BTG and the bittrex BTG wallet has been down for like more than a month. So for BTG specifically, if the MPH auto-switch port is mining it at all, you may want to not set it for auto-exchange and either manually exchange it on cryptopia yourself or accumulate it and wait for bittrex (don't hold your breath).
