mr exchange also known as Ripple is a Japanese cryptocurrency exchange that was created to help the Japanese to do cryptocurrency exchange, although there are many exchange in Japanese to use. But this project has no effect to the cryptocurrency exchange platform, it has sieze to exist and has warned it user's to remove their funds from the exchange to avoid any loss of funds. The project didn't last long in the community and it has no been known by people around the world and it has already lost it place in the cryptocurrency world. The project has developed so many issues so far they lack security and limited funds to keep up with the project. This project won't be helpful to any one willing to do exchange both to the Japanese citizen and other countries using the platform. The platform actually has a nice webpage which looks very good and looks like a functioning project. You can make your research very well it was said to stop existing in 2018, I think they had issues with the Japanese government
