First of all, altcoins are much safer than meme coins. 
Volatility, cheap, a headstart for something better, a chance to be a millionaire, unique projects. Different reasons I saw from different investors but mostly are for the easy money.
Buy it at their pre-sale and maybe you will hit the jackpot.
Others do tend to look for a cheaper price for something whole unlike with Bitcoin, you will just get a part of the whole from your thousands of dollars.
Your pick, your decision because at the end of the day it will be you who will reap the rewards not the one who told you so.
