I'm surprised no Chinese cities on the list, China has the most powerful exchanges、miners. In Hangzhou、Beijing、ShangHai, these cities also have many geek teams are working on new business scenarios.
The thing is, the Chinese government is the most unfriendly government in the world against Bitcoin.
After Sep 4, 2017, all Chinese exchanges have been forced to move out of mainland China.
The Chinese government calls for so-called "no token" block-chain.
They wanted to utilize the "Blockchain" technology but not welcome Bitcoin or any cryptocurrencies at all, since they believe that non-govementent backed crypto currency will jeopardize their financial security and lose the currency war.
