Countries with large amounts of virtual currency transactions such as China, Japan, Korean and India with the increasing trend of many brands continuing to expand their payment operations in Bitcoin, this currency will rise to a peak of $ 20,000 in 2017.
However, recent bad news from Asian countries Bitcoin price is going down very fast. Yesterday bitcoin price continues to fall deep down to 8,200$ and possibly more.
In particular, China and India have a great influence on the BTC currency because the number of bitcoin traders is huge
I would say among the countries you listed China has the greatest impact on cryprocurrencies, namely because several biggest mining pools are chinese.
This is a fearsome tendency since taking so much control over hash power goes against the main principle of crypto - decentralization.
