I doubt china will be in the top 2 when its all said and done. China keeps on trying to ban stuff related to crypto and just recently published a new desire to stop airdrops as well which they already explained their hatred towards ICO as well. So it means blockchain is improving all around the world while having setbacks when it comes to china, that's why it is hard for china to actually beat any country in blockchain competition.

Certainly not a big country like USA which already has many countries trying to build blockchain softwares to help out corporations on their needs. Blockchain software is now used in many third world countries like carribeans and bahamas and malta and so forth, it is quite soon that it will start to work its way towards first world countries and meanwhile China is just trying to keep its people away from it.
