Asia is very important for cryptocurrencies. Asia is also the center of the 21st century world. Many countries will rise, and China, India and Japan are very strong. The rise of cryptocurrencies is inseparable from them. The strange thing is that Japan fully accepts cryptocurrency, India's neutral cryptocurrency, and China bans cryptocurrency.
I'd also add South Korea as a very important country in terms of trading. South Korea is rather strict with cryptocurrencies (especially with ICOs), but willing to rethink its policy and is projected to become a very crypto-friendly country in the future. China is/was a major center of mining, but the current policy is very unfriendly, of course. Anyway, as for the main question, Asia used to have great impact on the market and a big part of the market's crush is due to various Asian news on bans and regulations. However, as for now the market is low but stable, I don't think that any country or region can make much difference. And let's hope it stays this way.
