A recent article reported that China's outlawing of crypto transactions backfires: more Chinese are turning to underground projects and decentralized exchanges without the CCP's control. Do you see global implications for the crypto market?
Trying to send its citizens back to the stone age era was never the answer for this. Crypto is here to stay and am sure the government ( CCP) were very much aware that there was a possibility of this going underground should they use their authoritarian style. For all I see is a missed opportunity to leverage the technology in their favor or perhaps find ways to tax and grow its revenue streams.
I think your usage for stone age era is not really that precise as they are not really living the "stone age" life right now, nor their lives will be such without Cryptocurrency. You are not touching reality by saying that. Instead you can simply say that Chinese citizens that does crypto will be affected in a way that they won't be able to have such financial freedom to choose in terms of doing investments. Surely they will miss the opportunity like you said, but not enough for them to go back living in caves.
