Short Answers
BCH can be mined.
Is there publicly available BCH miners right now?
Can my old Antminer XX work on BCH network?
- I think this is a possibility if someone starts hacking it or bitmain comes out and releases updates to older miner software. They may even be able to do it right now with a pool.
Can I mine BCH with my GPU?
- Yes if there is mining software out there you can find that will work but will it be profitable? Not until difficulty tanks on BCH network back to "GPU mining" days of difficulty on BTC (not likely to happen since SHA256 asics exist, SOMEONE will adapt one of the many that exist)
Will it be profitable to mine BCH?
- This question is subjective to difficulty, price of electricity, and hashrate you can create. You will need to answer this for yourself by doing some math.
In essence the answer to "How to mine BCH" is that right now we are in a phase of "hurry up and wait" on the answers. Rest assured, once someone adapts an existing Asic to mine this network, its going to likely blow up to BTC difficulty levels from a few years ago and probably be worth less than BTC was during the same time since BCH is an "ALT" coin
Please correct me if I'm wrong, but BCC is SHA-256 algo so any existing BTC ASIC can mine it. I just blew the dust off my S5 and about to point it to one of the pools available. Just have to wait for the difficulty to correct and network moving to see if/how the dumps will go to determine profitability.
Some of the larger pools like Bitmain is talking about directing some of their hashing power to BCC to support the network. If mining BCC requires different/modified gear, I doubt it's been Dev'd that quick to allow for a network hash if 5 Peta Hashes in a couple of days...
