That's some nice news, but it doesn't change the hypothesis. Also, it suggests that if he did allot of the buying, that there might still be a allot of money still left on the sidelines waiting for one more lower dip. If it were to happen, I'd consider it more bullish for the long term, of never returning to these levels of cheap BTC.
Roger does not have enough money to influence BTC, and BTC market cap is too large. Its a lot easier with some financial backup to create peaks in BCH than in BTC given their market cap.
BTC has too many good news on the way, I think BCH has nothing more than a bunch of crazies to control it; institutions are struggling already with BTC, do you really think they will put their money on a coin controlled by people with such a track record?
The only argument you can make here is that BCH is funded by big financial institutions trying to control BTC, but if that was the case, I think BTC would be dead already
