You should know that not all atlcoins listed on major exchanges are worth investing in, anyone has seen the damage to the luna coin because it was once on the top altcoin list and had high liquidity on various exchanges, but the luna price breakdown was the worst in crypto history this year, so we should consider investing in altcoins and should review them every latest news update.
I agree that we should be picking coins that are solid, but people not knowing Luna may crash is their own problem. Last year in 2021 there were a billion algorithm stablecoins that crashed because if you keep on selling it, and making money from it, the market can't recover it and all that money stored aside will not be enough, eventually there will be someone richer than the money stored who will keep on selling more and more.
Last year I was part of a project that had 30+ million dollars like that, and someone with more than 30+ million dollars came in and destroyed it and made money along the way and it never recovered. When you do that to UST, then Luna goes with it obviously.
