It seems very simple, only 1% of the profit margin is targeted per day of the capital you use in trading, but traders will not use the entire capital they have in one trade as it is done to anticipate if the market turns in direction, so they will usually only use about 20% of capital that traders deposit to the exchange. So the goal is to stay at 1% margin of profit or the amount of profit in fiat, if the target is to remain in a percentage not in the amount fiat then how much capital you use no matter only profit will obviously depend on its modality, and that you should know no routine profit you can be traded even with only 1% margin profit in crypto because the market is often unexpected, and if it is a copy trade just have to be careful enough to choose lead traders by paying attention to their trading statistics as a picture of whether he is good enough to be a leader in your copy trader.
Copy trading can be profitable that’s why the exchange holds this feature but depends heavily on your lead trades.
