Yes i like that too, There is more money needed for short time investment. For example I can say, When bitcoin value was $5000 then you bought 10 BTC. At list when Bitcoin price rises to $6000 then you can sell them. Follow keep your some profitable about short time.
But short term trading is not as easy as you said here. It will take some time to reach the 6000$ price and later you need to be fast for selling the BTC before it drops. It is time consuming but short term trading has some advantages.
