it can be mined with GPU,only the time and electricity wasted to do it
makes the process totally useless,BCC has difficulty comparable to bitcoin,so it makes no sense to mine it with GPU
besides,there are altcoins that are much more profitable to mine with GPU's,just go to coinwarz.com and pick one
IMO it's fine to have choice. BCH still exists so if people want to mine it they can go ahead and do so. Considering that you can mine it with BTC hardware it makes sense to have an easy way to switch.
this BCC difficulty jumps,that have nothing to do with Satoshi's whitelist,by the way
are exceptionally detrimental for BTC,as it makes the miners switch to the most profitable coins to mine
thus making the time between the bitcoin blocks extremely high and thus causing the mempool backlogs
then it returns to normal and BCC blocks come out empty
I hope there will be no more cash to support buying out al lof the dumped BCC coins and the price drops substantially,so it does not impede bitcoin's growth
