Its impossible for the bitcoin end this year, because eventhough many countries banned bitcoin still bitcoin is very fast to recover and not just only that bitcoin also increases even the China banned it, imagine China has the largest population in the world and just think how many people using bitcoin in that country so it is impossible that bitcoin end.
China and any other important and non important country have no control over the network of nodes, while you are talking about possibility of ending Bitcoin
The same countries are buying the coins, they didn't really ban Bitcoin but told every exchanges operating in China to stop trading, they told them to acquire
Licenses to know who is buying and where they will cash out fiat, that was an excuse to buy more for their own benefit. governments do this all the time.
