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)
Short term trading is very difficult to do. If you are looking for 15% profits every day, then I will say that it is still not possible. You can get this amount sometime but you can't get everytime. I usually like ada, xlm, doge, xrp for short term trading and my daily profits is 7-8% but not fixed everyday.
