For the short period of time China traded without their usual zero fee bullshit, their volume was less than the West. There's nothing there other than gamblers and miners. The UK has more full nodes and that has a pathetic Bitcoin scene compared to the US.

China has no developers, no merchants, no usage. It's been gone throughout the explosive phases of this rally. If Chinese miners are exterminated, Bitcoin suddenly looks an awful lot healthier without those 10-15 people controlling all of the mining.

As for the ETF, there are tax advantages and there's nothing to learn. You just buy it and hold it through the conventional channels that millions of people invest with. That's a biggie.
