Bitcoin has become the most popular cryptocurrency in the world. Some countries allow the transaction of bitcoin, but some countries prohibit it. China belongs to the latter. Why does China shut down bitcoin trading? Let's analyze this problem today

However, the rapid rise of the current price has formed speculative anticipation and may form a bubble in the future. Therefore, it is necessary to take measures ahead of time, which can also restrain some illegal acts of laundering money and transferring assets through bitcoin. p>
