some people might considering finding coin like doge and shiba inu to be easy but honestly its kinda difficult because everything is just so unpredictable with these meme coin surely nobody know that some random meme coin on solana might increase that much, most people are just accidentaly investing in those and make it big.
so as you said, investing in meme coin only worth it with spare money that someone can afford to lose but even so, considering all the manipulation going on, i would think that the odd are pretty low and unfair with meme coin in general, its just full of some random dev manipulating liquidity and all.
might as well invest in something that makes more sense, with some new altcoin maybe, at least they have something to offer and you should just patient and then you will get some rewards.
