This is not the real segwit 2x fork. Its a completely different team, it has 4mb blocks (instead of 2..hence 2x..), x11 encryption algorithm (SHA56 miners are useless) and is premined. If you want to put your bitcoin on an exchange for another useless hard fork, be my guest. Otherwise, stay away and if your hardware wallet supports it in the future, split it safely at that time!
