now what we see the future of the altcoin has not been said sure, market in a state of bad trend even though the market is currently bad it does not mean there are no altcoins that can rise up to hundreds of percent
Any coins has no guarantee future, even BTC.
What your decision is only based on your speculation and prediction, other people might have a different perception on the future.
It's quite normal that when people give their prediction in the future, they just based on the current situation.
Just like when they think bitcoin will moon hard in 2017 when the price already has moon enough, they don't see the correction coming.
