Because when btc moons, the dead alts can rise momentarily only
I only witness a bull run once in my life but I have some regrets for not selling some of my assets at the right timing.
if this would happen again and my dead altcoins will again rise, I am sure I would not make the same mistake again, so hopefully it will.
i do not think that dead altcoins will raise again, not briefly, not anytime or anywhere, but there are plenty good altcoin projects, that will follow suit with BTC rise due to halving and scarcity, because those altcoins are bringing new value to this market and industry, and providing value for users
somehow, for me, most important thing for altcoins is are they used or not, and is there any money on a daily basis that is spent on their networks
