Before you pick sides consider the following:
Amaury Sechet (ABC Dev) & Gregory Maxwell are buddies.
Jihan(bitmain) is a major investor in Blockstream.
Trezor(core troll supreme) supports ABC.
Please open your eyes
can you give a proof that Bitmain is a major investor in Blockstream?
I do vaguely remember their logos comingled. I don't believe Bitmain cares that much about keeping Bitcoin alive for the long term. They're in it for the fiat(and possibly communism).
