For me the risk on long term investment in bitcoin is not very risky at all because you will just wait for like 1 to 2 years or more. But if we are talking about the short investment then it is very risky because the price is becoming unpredictable even more though all of this is base on my speculation.
Yeah, Bitcoin is pumped capital into lots because it is gradually gaining trust and expanding its popularity in the market, that made new investors realize the value and potential of bitcoin, they have started investing in bitcoin, so investing and holding bitcoin for a long time will not be too risky, but remember that for a long time does not mean too long, we should sell it at the right time. We should not be too greedy and have blind faith in Bitcoin, sometimes this can also bring good results but sometimes, it also brings bad results, careful and remember safety is always a top priority
