Is there a hands down best option for hardware? Does anyone know whether the Z11 would be able to mine ETC, or is it ZeCash only?
When checking for compatibility, look at the miner's algorithm.
Antminer Z11 is for "
Equihash" algo while ETC (
Ethereum Classic) is "
EtHash", so it isn't compatible.
If you're targeting Ethereum/Ethereum Classic for ASIC mining, it's a bad choice IMO.
They are known to fork whenever there's an "
ASIC risk"; if they fork after you bought your ASICs, you'll end up mining another coin.
