I think investing in most cases is a risk. But looking at how the market behaves, we can say that it is very volatile and after the fall is a price increase. So I think everyone should decide for himself without listening to third parties.
It's or decision whatever we hold or we sell, but in times when the market price pulling down its better to hold our asset like bitcoin and other alternative coins. There will be no loses of your assets, the only change was the market price. Remember there are always a risk, the only thing we can do is take it.
