The website MMM-Russia abolished the Mavro currency conversion. The reason was the abuse of this feature by some unscrupulous participants using it as a platform for currency speculation without failure. Initially it was introduced a few months ago, so that participants can use it to offset the speculative exchange rate shocks in the global markets. However, there were many members who took advantage of the technical delay of displaying exchange rates on the system’s website, which made this a safety feature for predatory fish. Sergei Mavrodi’s decision is that the most odious hustlers, whose number of conversions exceeded 10 thousand have been removed from the system without the right to participate in it anymore. Despite the fact that it was not officially forbidden, these actions were regarded as a violation of the spirit and ideology of the system, created to help people, and not pumping out their means.
