How convince my friends to buy productive coins like ETH instead of Dogecoin

All my friends recently got into crypto but they keep falling for every new Binance shitcoin that pops up and sending dogecoin updates in the group chat. Im having a morale dilemma on whether I should really put in some effort to explain to them that most of these coins are garbage and will hit 0 during the next crypto winter or should i just let them figure it out.

I've been leaning to the latter but I feel like throwing them to the wolves might just discourage them from crypto but like the alternative makes me come off as a buzz kill.

​

Does anyone have any advice on how to handle this?
