No, I will not trust any new altcoin but I trust some altcoins because not all the new altcoins are potentially good but there are some good altcoins as well and I've gotten new altcoin results and that's a lot
Everything you believe, you must follow because everything is for you and not for other. You will bring profit or loss for yourself.
For me, we need a proof to believe something so i will trust the old potential coin like etherium rather than more believe to new altcoin.
