i've been also wondering why bitmain is pro segwit with litecoin, but they are against segwit with bitcoin
i think the answer is clear now, with litecoin they have not all the fee because there is no delay in transactions due to the block being already 4 x before segwit
with bitcoin yes, so they are just greedy miners that want more money and nothing more
If Bitmain want bigger blocks, Jihan said many times he wants bigger blocks, then why do people go on about bigger fees, greedy, etc. Bigger blocks will result in lower fees but more transactions. The increases in transaction means more accumulation of lower fees. This is a win win for miners and users. Presently miners are the winners and the users are the losers due to 1mb limit.
Jihan can say he wants to take a bite out of the moon because its made of green cheese, that don't mean he really wants to do that or that he really believes it. What Jihan really wants is control over Bitcoin so he can make more money. All of his actions have been to this effect.
