Don't chase after big benefits. I think point of short-term is quick money, not always big. Just check the rates and predict its tendences for nearest time.
Short term profits are tend to be low and don't expect something big can come out of it unless your capital is quite high. But risk in short term can be measured depending on how good you are spotting a coin that can fluctuate daily.
The process of making some profit with short term is you should look after those coins that came from dip.
