Mr. Exchange is the new name of Mr.Ripple. The exchange is still in the transition process, which may be the reason for the multiple problems they are experiencing (most notably, some users not being able to withdraw). This is definitely not a trading venue which we would recommend for non-Japanese traders (in fact, the locals should also proceed with caution). Hopefully we will be able to update this review in the future, when the situation settles – we are sad to see the gentlemanly logo be associated with such a project.
