Would we expect less from Japanese lol? Wise people will know that this can be a perfect chance to have a nice investment since the price is very affordable and can't really get much lower than it is now. People are panicking and cashing their money to save it home, mostly thinking that the crisis will have a huge influence on money liquidity, we're all seeing what this worldwide panic has done, people are acting without any proper thinking and Japanese got enough gray matter to make the correct choice lol.
I have genuinely never in my life seen any trader anywhere mention JPY volume or pay any attention to it. That says enough about adoption and interest there.
reports measuring the volume by countries always state China, Korea and Japan in the first places also we can't except a large adoption there, by the end, it's a small island compared to china.
