I don't actually think their laws will get rid of crypto.
A single country law can not eliminate bitcoin, see the recent last China FUD, bitcoin was down $5% to a price around $41000, but just few days after, the price soar to over $50000. Bitcoin price now at $57000.
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, Monero is regarded as anonymous coin. 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.
The battle of bitcoin is against the world leaders at large. It is not only against China. Till bitcoin begins to fight back, China will loose nothing.
I do not think so. One thing about bitcoin is that individual have their opinion, you will see a leader that will support bitcoin while another againstimg bitcoin. That is just what bitcoin. Another thing is how a country is operating, we can see how Donald Trump do not support Bitcoin while Warren Buffett is a bitcoin critic, but yet USA have the highest number of bitcoin ATM. China is more subjected to control by force from Chinese government.
