bad decision, memecoins are very volatile it was better to choose ether, btc, bnb, solana, more stable coins for the first time

I need help from those who have been in this for longer, I always wanted to get involved in this world but until recently I was underage, even so I have learned a little, but now I have put all the money I had into these two options, do you think it is a good decision? I don't know what to do
