After all the regulations from the Chinese central bank,i guess that most of the traders with accounts in chinese cryptocurrency exchange platforms moved their cryptos to Japan + more and more japanese started buying due to the btc adoption.
I`m wondering about this.Is China still the number one country  for cryptocurrency mining?
Perhaps they mine bitcoins and sell them to the japanese.
China is not the world leader in crypto trading anymore and this is good news.
There were so many people here asking "Is China manipulating bitcoin?"The answer is NO.
Anyway.The future of cryptocurrencies is in Asia for sure.
