People don't want to give projects some time to grow, they forget that coins like dash, litecoin, Xmr, Bitcoin etc have a rough start, I'm just saying crypto investment takes years, just because a project drop in value doesn't mean they won't grow better in future.
Projects don't just turn huge in a year, there will be lots of volatility and price loss, for long term hold be prepared, if you can't then go for top coins
Like any other investments, it should really take some time. But the shorter the time to make a profit means more chances to reinvest your money. It's less stressful to hodl and put your money on the top coins, but then this can also give a lower yield since the risk is lower.
Volatility can give you losses but it can also give you more possibilities to make profit.
