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
But most of project launched after 2017, get scammed. I bought some crypto currency but got drop. I know team need time to develop and promote their project and that's why i Give them too much time to hold but after 3years later now, nothing changed but drop more and more.
