Short term for me is much better and more profitable but with a great risk compare to the long term investment. Long term investment is also profitable but all that we can do is to wait until btc price will finally rise.
Especially in the bearish trend and short term investment will be much better because if the price will be recovering again soon and then we can try to take our profit and walking out asap to secure our amount. Long-term is very risky right now. And i think that short term can catch the momentum on the bearish trend.
Well it really depends on the person doing the investment. If he is good in waiting then long term investment could fit him, he won't need to check the price every minute since his money's welfare will be judged on a given time but if he doesn't have patience then short-term is the other way around for him to earn profit in here. I personally take short term investment riskier than long term because the price could change any time plus the fact that it is also time consuming because you will have to give time watching the market.
