What do you mean by eptocurrency, I would likely assume that to be a typographical error. All you have said is true, as everyone here on this forum already know about it, so I don't see why you aren't telling us something we don't know.
Of all the existing cryptocurrency, Bitcoin has shown to be much more profitable with a market cap over $ 580.02B USD and most people would usually invest in it. Other cryptocurrency or rather altcoins are still in the early stages of development, and their long-term success is uncertain.
.Again, if its value suddenly decreases, there is a possibility of loss.
Not just Bitcoin all cryptocurrency.
