According to Wayi, the Bitcoin ban in China will be beneficial to the digital currency's development internationally, as the ban will significantly curb speculative forces originating from the mainland, contributing to much of the wild volatility it has seen recently. A more stable Bitcoin will better ensure the interests of its users, said the company.
Volatility is not caused by chinese investors (unless this Taiwan company can prove it?) and China mostly out of the game is a negative news for bitcoin.
