Most developed countries have already legalised Bitcoin (except China) so we can see a good trend, other countries will probably follow, they can't ignore the future and they are not fools
China is not the only country that banned Bitcoin. In fact there are also a lot of countries you don't know that banned Bitcoin especially the countries with internet censorships. China is a developed country, in fact it is one of the greatest country in terms of the market so I don't think you need to belittle China.
