I'd be interested to know why he feels the need to bad mouth the competition. It seems to me both btc and bch would do better working together than being at such odds all the time. I'm no expert but yesterdays fiasco smelled of a coordinated attack (the timing was too perfect to be a coincidence) and now the entire crypto community is suffering for it. I get they want to be number one but.....seems to me performance and unity would go further towards achieving that than this constant antagonism.
Oh, and great get on doing it here first. That really is a coup you're pulling off for the benefit of all of us. Seriously, thank you!!!
The two tokens are being traded for one another and both have good liquidity, so it's not strange if one rises when the other falls considering that they are now working on different principles. People try to swing trade both or to hedge their bets.
"Bad mouthing" can take many forms. For years now BTC developers and supporters have badmouthed dissenters, censored debate and manipulated the public in many ways while letting the blocks get ful in spite of this not being necessary and going against the plan of Satoshi. It continues.
The difference is that blockchains are a competitive space. When the product is not delivered, others fill the deman.
