No I don't agree with u on this, there are many altcoins which are worth investing for long term, yah am talking  from experience, investing in fundamental coins is very beneficial in the long run.

Take the L1 coins for instance, coins like solana, BNB, $Near are all doing fine in the long run, immediately people get know about their importance boom  there go parabolic. And presently there is a new trend of altcoins which is the meta verse tokens, we can see coins like AXS, sand, PYR are all doing very well and for the long run they will keep yielding more profit for investors.
 Play to earn games are really doing good, and my new catch is Hash Rush.
