The reason you gave here is not enough to convince people in those countries to make use of cryptocurrency. And FYI China has banned Bitcoin for good and I don't think they are going to be accepting it any longer and if they do its going to be under regulation (oh, what am I saying… Bitcoin can't be regulated right? That means they are not going to accept anyone making use of it. That's why a lot of crypto companies are moving out from china and moving to other countries where they will be allowed to continue their crypto business. Let's wait and see what the future holds.
They have been doing so for the past 4 years, and believe me, from all the bans they have issued against bitcoin and cryptocurrencies, the Chinese crypto community is still one of the largest in the world. The recent bans that they issued were all focused on mining due to
environmental concerns and does not tell anything regarding trading, holding or keeping the said crypto. Business as usual for the Chinese people even though their government tells them not to.
