It's a ponzi scheme. Stay far away from these crooks. YSLM was MLM company that was committing investor fraud. Multiple government taskforce went after CEO who was arrested in Thailand. He made bail and is on the run. YSLM renamed to Monspace appointed new CEO and continued the scam. Different name, same scam.
They charge something like $200 for membership in return you get 117 MSD coins meanwhile they have no source code, block explorer or any other way to verify coin supply. Some in the troll box have said 30 billion others 4 trillion.. we'll never know. To boot, they locked Monspace wallets so that they (Monspace/Tidex) can dump their coins on ill informed investors.
