Recently, I heard that China banned holding cryptocurrency and cryptocurrency transactions, so does that mean that having cryptocurrency in China would be a criminal offense? Moreover, why create such a ban in the first place?
Regarding the law, this involves complex rules and regulations. Don't be affected by issues with unclear sources without clear facts and sources. This must be studied more deeply, by making the applicable laws there a clear source. As far as I know, China is quite open with cryptocurrency, not fully banned, maybe there are only certain restrictions to be able to control the adverse effects that might occur.
