Either way both of those would depend on Bitcoin anyway. There are many shitcoins out there so I am not sure what you mean by that alts are safer than meme coins, since both of them are volatile in the end. Only other thing I can say for meme coins is that it is hyped so bad by many influencers out there.
I never saw nor heard an influencer pumped a random altcoin still.
Who knows though I don't care about these type of coins anyway.
