I hate altcoins, they made my dad lose money and they are just imitating bitcoin, a lot of altcoins are just to scam money and then disappear, and the real king is bitcoin. So I call on everyone to join me and only believe in Bitcoin, abandon those altcoins that cheat money, and just follow it!
Don't blame those altcoins but instead your dad's action. Bitcoin is the King and there's no doubt about that but if you play it right, there are lots of worthy altcoins there. You don't have to stick with only Bitcoin if your goal is to have a decent outcome in crypto.
Open your mind and explore things. Your crypto journey should not just be limited only to Bitcoin.
Nothing wrong though with that if you are not comfortable with other altcoins.
