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)
for current market conditions 15% profit is still difficult to get, we know if the current position of trading depends on where the coin price grows rapidly and we cannot control the daily profit target.
ethereum coins are the best choice for me to trade.
the best hour is when you trade
for problems the profit may be 5% good for daily profit when you see unstable market conditions.
