For me it's not a lose. The best strategy is sell at the peak and buy at the dip. You never know what's coming so better to take advantage of the ups and downs. But this is only for people who has all day to monitor the price of bitcoin but if you are a long term holder then there's nothing wrong.
The thing is long term holder is more or less sure to make a profit but short term traders can lose just as quickly as they earn. Personally I don't believe there are many traders that consistently make a profit so I would always advise people to just hold on to their coins.
There is no difference between them people are came here to see the difference if i tell you something in very simple words. So i would say that long-term investor struggle for their future while short-term investor don't struggle they just sell and earn some extra profit then go for another coins as well because they are only looking for money.
But in my point of view, long term investors definitely get more profit than short term investors. Because now i thought if i never sold my all bitcoins than in this time, i would be gotten 90% profit from my actual use of money. In 2015 i have 10 bitcoins and with the time, i sold them and now i have only 3.5 btc , now you could think that if i hold my all bitcoins then i would be gotten biggest profit from them.
