OP posted about altcoins being dead last year and it's most likely that it became better after a year. But not all altcoins have and will survive. I think that there were a lot of them that have been dead forever. I also get the idea from some people that if it's about investing to any altcoin will give profit, it's not always the case. We're not yet on that season and by people mean anything, don't be too gullible with such words because it may just lose you a lot of money.
Just like you said, last year, there were a lot of dips in the market and some altcoin dumps, and we couldn't survive them. According to the OP, even the altcoins he gave as examples are still in the market despite the fact that the price is not very bullish, apart from ETH, which is still doing well. The other coins are not yet permanently dead.
Altcoins could be investments that favor some people while others might not be favorable and can cause losses. That's why investors are advised to invest more in Bitcoin or to have better knowledge about the altcoin market before investing in altcoins.
