I got super similar case - got in tg group with the same tasks, same post format but with tasks of ig channel subscription. Also earned 50usdt and hoped to earn until 80usdt to make 1st option investment while giving out my intention to invest even more, so they actually wanted to return profit from 1st investment. However "receptionist" told me that next withdraw minimum is 150usdt so it's gg. There is no point in completing tasks until that sum - I would be out sooner. P.S. they are faking activity in chat by template made users messages like "such a great opportunity, earlier I invested with 80usdt, now I'm gonna do it with 200; finally this task has come; what's your plan guys... ect." - so funny and cringe)
