Was this a trading platform sczesw.com Gemini Pro.  Trading on minutes of currencies

Bitcoin , ETH and so on.   Showing 95%  gains from an analyst, then say you make 52,000 in your USDT but you can not get the money because their agreement is the commission has to be paid first which is 20% of profits.   Now, you can not take it out of your profits / earnings they want it cash out of your bank account before they will release any of your profits.  So say, for this amount of profit $52,000.00 they want $10,400.00 sent them for commission.  Then I hear of people trying to get their profits but will not go through, also, telling them they have to pay taxes of 15% if I recall.
