now it got only 20k unconfirmed transaction when the bch bump it was 200k fake transaction +
Those unconfirmed transactions were actually not fake, miners have left bitcoin mining and started mining bitcoin cash because they were getting more than what they can get from bitcoin mining. So difficulty was high but number of miners were low so transactions with quite good amount of fee also got stucked for few hours.
It seems more than a coincidence that miners left Bitcoin for Bitcoin Cash at the exact time that the segwit2x fork was postponed and a load of transactions hit the blockchain and the Bitcoin Cash price skyrocketed.
It seems like it was an attempt by someone to get the Bitcoin Cash price up, or maybe even a shot at the number 1 spot.
I guess it doesn't really matter too much to miners if Bitcoin or Bitcoin Cash is number one, they just point their miners in a different direction.
