If I deposit ($ 1,000 for example) to any Trade Group today, when will I get profit and how much exactly?

You will get first profit next day after 00:00:00 UTC before 00:06:00. Profit volume depends on the investment Agreement with specific Trade Group. If they offer 0.1-6% daily profit, it mean you may get 0.1%, or 6%, or any percent in the range from 0.1% up to 6%.
