I'm sure the people who lose when invested in short term they don't intend to invest in cryptocurrency. They just like profir and promissing have invested in cryptocurrency. They don't understand the risk, they don't understand the volatility price bitcoin and cryptocurrency. Just put money and wait a second look price go down they sell, that's it.

But I'm prefer to invest for short term, why? the reason is I take my brain calm down, I wouldn't make my brain see the price continue to decline. Yeah I think it will make me stress, so I will buy bitcoin when the price down and I will sell bitcoin if price up. Sometime we need lose for make learn and have strategy like this.
