I don't actually think their laws will get rid of crypto.
But discourage many people from using/owning cryptocurrency.
The CCP has planted the seeds of the rebellion that will throw them out of power and they don't even know it.
Obviously they know since there were many similar attempt.
Instead, people who don't like being under the harsh thumb of the CCP will utilize privacy cryptos like Monero
If you want privacy, you can use bitcoin, but you will have to learn ways to have maximum privacy while having bitcoin, Monero is regarded as anonymous coin as no open ledger for transactions. Also, did you think Chinese (the citizens) will never use bitcoin again? They will and Chinese government will bring up another FUD. Bitcoin and decentralized currencies are not easy to restrict.
While it's true, Monero is preferable option since user carelessness is less likely to reduce privacy.
