Will you be running your game in China?

This will be useless. Cryptocurrencies are restricted in China.
But other asia would work, I think.

Who told you this? I've been in China and the gov is not against crypto in any way.

Is there limited Internet in China? I do not think so.

Yeah but the crypto is very popular there

There are not that many people who wants to invest money, most of crypto enthusiasts there are just miners.
