Nowadays many people buy dip and sell it back to the pumping hall. May take longer or less time to reap benefits. It totally depends on the investor. Because an investor will depend on how long he will hold his investment. But usually I keep the investment for a long time and it is able to get the maximum benefit, because the longer the investment period, the higher the benefit.
Funny enough I don't believe that anyone who holds his investment for less than 4 yours is a long term holder except on cases where the person was able to accumulate so much bitcoin in such a short amount of time and maybe was lauck to invest in a time like this(for those that started invest maybe mid last year or from last year). Why short term investment is a abuse to investment and rather trading is because you are not following what an investment should be, how would you buy low and sell high without letting any compounding effect come on you investment.
