Guessing this means the top 3 cryptocurrencies.
89% of all mined bitcoin is from China. Assuming CCP control all that means they can do a 51 attack as they mine the majority.
China is the undisputed world leader in Bitcoin mining. Chinese mining pools control more than 60% of the Bitcoin network's collective hashrate. Not only does China manufacture most of the world's mining equipment, but massive mining farms are located there to take advantage of extremely cheap electricity prices.25 Aug 2020
Mine a bunch of coins, send them to an exchange, convert them to a different censorship resistant cryptocurrency
or stablecoin, withdraw those funds, then release a bunch of blocks that were mined in secret that send your original UTXOs that were spent in a deposit to the exchange back to your own wallet.
Bitcoins whales are likely Chinese too, there were rumors 5 years ago of chinese coming to the USA with "bags of dollars" to trade for BTC.
Which means BTC is now an extension of the chinese currency Renminbi / Yuan. People are, en masse, swapping their USD for BTC which devalues the dollar and puts the dollar into CCP ownership. It wasn't a problem until recently; institutions buying huge amounts of it.
BTC is now an extension of the cold war between china and the west.
Hence the EO banning security trading with the CCP; I would guess BTC comes under this at institutional level. Probably CCP only because the West doesn't want to be seen as picking on the poor Chinese citizens under Chinese dictatorship rule; but China itself. As you can see here the top region where it's mined is the region where the most atrocities take place; CCP hub

3-1 I would guess means China own the majority of BTC, Ethereum, and either Ripple or Litecoin.
I've always favored Monero. It's actually anon and it doesn't follow the same pricing as btc. It's far more stable. I regret spending mine on "substances" back in the day instead of saving for now.
