 Evolution had earned a reputation not just for its security, but also for its professionalism and reliability, with an uptime rate much higher than its competition.Partly for that reason, when the site went offline a few days later, on March 18, the user community panicked.The shut down was discovered to be an exit scam, with the operators of the site shutting down abruptly in order to steal the approximately $12 million in bitcoins it was holding as escrow.
