Who will finally be the Blockchain Leader in the world; USA or China?
it is hard to tell since both country has its own potential in that said technology, the best thing to do is to develop it and help the market to be known in the world and used it as a mode of transaction, since both country has a better influence than the other it will really affect the market once they are develop it for better.
China will excel because they tend to improve quality in line with developing regulations, while the US is more concerned with the quality of regulation before actually announcing it to the public.
I mean from the side of the actual blockchain testing and faster development will be carried out by China and in the end the implementation will run in front of other countries.
