why need to wait for the lowest when you can purchase in the midst? this is the problem in people that have so much greed in it , they tend to lose chances because of waiting for multiple income so they ended up being locked in that expectation.
if I am to answer? buy now mate or lose your chance of making money in the coming months.
OP is right to some extent, altcoins are very deadly investment and equally they are high return investment project depending on where you bought it, if you buy it at lower price with low market cap, a small liquidity will give you an insane profit so big that you will never imagine but the are rare these days, this is why you must be careful and do proper research and buy when the price is low, you may buy in the middle of somewhere and some people will dump on you.
The only altcoins I can recommend for someone to buy is top 10 altcoins, you will see Solana, BNB, Matic and some later 1 coins over there, you will have peace of mind buying them in the middle than buying altcoin that aren't even popular yet. Sometimes, you would find it difficult to differentiate between meme coins and real projects these, investors or should I call them gamblers prefer meme coins these days than normal projects.
