It is likely the money obtained via recent Bitcoin crash that got pumped into BCash. Let's not forget that Roger Ver has sold his Bitcoin stash recently. Now he and his minions may have decided it is right time to prop up their bastard child. Their short-term goal is to make BCash more attractive to speculators in these unsettled times.
If could very well be that they are pumping Bitcoin Cash so hard right now and make easy profits. And for those who have ride the wave, sooner or later, they will go back to Bitcoin after taking their gains. Bitcoin Cash will remain the poster child for Roger and his cohorts, pumping it then exiting at the perfect time. Newbies, just beware, you don't know how this game is played, don't be trap and exit as early as you can. Overall, Bitcoin Cash still doesn't have enough traction from the community and never will. I'm not riding with them, would rather trade with other altcoins or HODL Bitcoin and wait it out till it bounce back.
