They said that Bitmain and Roger Ver were going to sell off their bitcoins and put the money into BCH after the fork and they are probably doing it right now.
Who said this? A businessman will always be wise as a businessman. Why would they gamble their thousands of bitcoin for this new creation? It's just odd that they will let their profit go into the thin air, no way they won't do it. Probably they will but maybe 10% of their total bitcoins.
That is why the price of BCH is sustaining at this moment. Once they run out of the capital from selling bitcoins, the price of BCH will probably drop.
Not only because of them, traders will always be traders. Everyone is just chasing for the profit.
If BCH made it and survived with a decent price, that would encourage more similiar Bitcoin split in the future - which is not a good thing in my humble opinion.
Splits are giving the newbies fear and let's hope there's no more in the near future.
