I always believed in the short term positions and to be honest they are actually good way to grab bitcoin or any coin with lowest rate and then re invest the coin or fiat that we have gotten that way. You see it through my perspective, if the coin is not stable for pretty long period and we saw many ups and downs then we can always buy the coin when it is in crest and sell at trough and if we see another dip surging afterward then just buy it with those coins which you got as profit from the first trade. So thats how one should use the short term positions. Very beneficial if we keep repeating it ever.
I suppose, short-term investment is always there though Bitcoin always rises. So I do not think Bitcoin's price affects short-term investment. For example like ICOs, trading, tokens, and so on. It looks like a short-term investment if we take a good look. ICO is a solution for those of us who want to make money with a quick investment. There are some people who can benefit 1000 times as much because of ICO. But remember, not all ICOs are legit and profitable, there are some scam or fraudulent ICOs because they only utilize the popularity of cryptocurrency to deceive.
