Short term positions are always most vulnerable when values are increasing or decreasing rapidly because that's when there's the most volatility. On the other hand, it is also when the most profit is to be had for people who are successful with their trades and in that sense it is a double aged sword.
Short trading is very risky you really have to watch the price movement of every coin. Personally if you really want to experience the real growth then HODL bitcoin, and make yourself busy to other things, yes you are making money through that but you are wasting your time because you can't buy bitcoin as the same price in the past.
It is very risky but that does not mean that holding bitcoin is the best strategy, it is the best strategy for those who are risk averse or for those who are not successful enough with short term trading. But for those who want to gain large amounts rapidly then you should definitely give it a try.
