i think so risky if you Holding bitcoin a long time , may be just 3-6 Month it's good . but , if you already got cheap or profit you should sell your bitcoin , and waiting dump again .
Holding bitcoin in a long time is risky. The price is not stable.We can't predict what's gonna happen in the future. But if you want to take the risk holding in a long time, go for it. It's either you gain more profit or you gain losses.
