it is very difficult nowadays to benefit from short-term trading,. even a 15% / day profit becomes impossible for the current price situation..
there may be some trading strategies that you can suggest here. bittrex is the place for me to trade
1. what coins you use for short-term trading
2. what time do you usually trade
3. how much profit you can with your strategy (profit / day)
My strategy is very risky but offers its own advantages, this strategy multiplies a small increase in price with a larger invested capital to make more profits within a specified time, thereby reducing the amount of time you spend in the market also reduces the risk of uncertainty that could happen when you stay longer in the market, the risk is that if the price goes against you, you would be in much deep loss. If you are applying this strategy make sure to do your research and calculations well before attempting it.
