I received a notification email on April 17 so I thought they didn't leave this project but indeed their performance is slower than in previous years
I believe that the users who so ever invested in Taas would had already been in profit after their investment in USD. I remember that Taas users used to get profits in ethereum every month. It was kinda cool, dont know the exact scenario now but they never see to be a scammy project, they invested in many good projects and many of those were a Home run.
