Lol there wasn't such thing as currency in Soviet Russia/isn't in Communist China? What makes you think the currency aspect conflicts with the ideology?
Yuan doesn't exist I guess lol
BCH is censorship resistant. Your examples were heavily censored.
Communist countries can't tolerate resistance to censorship. Case in point, China just DDOSed Telegram, because it was being used to organize Hong Kong protests.
*Totalitarian* governments can't tolerate resistance to censorship. Social media has been taken down numerous times in capitalist countries, just look at Turkey, Egypt, Russia, Iran...
