Major roadblock is ABC wants to hardfork every 6 months which means theyd have to patch all their software or possibly scrap entire projects. Also they're extremely suspicious of China
So there's definitely a geopolitical aspect to the ABC/SV split that a lot of people are overlooking. Personally I consider China to be just a super massive version of North Korea.
Also, China is basically straight fascism these days. It's "capitalist" but the government picks all the winners and losers. So bitmain is a really big question mark to Japan investors
They're extremely good propagandists. Communism and lying go hand in hand I guess. There'd be no need for censorship(the great firewall of China) if they didn't have anything to hide.
That would be the "pot calling the kettle black". China is interested in manipulating all major currencies and commodities. Anything that threatens them or gives them more power.
