Well, expect big from the nation which is one of the super power of the world thru their military and economy, that they have also their own version of advance technologies that far superior than other nations in the world, that if China survived of having their own internet and websites, then how much more in crypto currencies in which they have ensure that all investments are purely legal and purely will benefits the Chinese people?
Well, they are successful in having their own version of those famous sites because they don't want to just adopt something but they wanted to make their own. It would be the same for cryptocurrencies as well that they wanted to isolate it because they wanted to control their people. I don't think that Chinese stop there though because they can still do something about it like having a VPN perhaps so they can still have access to cryptocurrency or if they really wanted to have a legal standing in it then they can go to neighboring countries wherein cryptocurrency is legally recognized.
