They are not anymore going back to the mining of BCH because there the same level of difficulty comparable to Bitcoin and the operation is not yet that profitable. I think others have also complained of the same problem. BitcoinCash (BCH) has to explain why is this so.
there is a simple explanation-the difficulty is same as it was with the bitcoin chain
it is hard to mine blocks with only 5-10% of the original hashrate,so the miners will be waiting for the adjustment,meanwhile,BCC
will be experiencing some long confirmation and in between block times,it is only reasonable at the moment to keep mining bitcoins,because the difficulty is same,the price is 7 times higher
BCC is being traded at 0.15 per token at Viabtc,volatile as hell
but things might change soon,after the difficulty adjustment,miners will be calculating and redirecting power back and forth
either that or BCC will be dying a slow,aka Bitcoin Classic death
