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 really not comfortable with other altcoins or have a plan on extending your knowledge with those.
Everyone basically has their own thoughts on things like this.
Bitcoin is king now and it has been for several years now and will likely remain that way. As for altcoins, there are currently a lot of projects out there and even though most of them are useless things, we also can't rule out altcoins in this regard.
We know that different heads must have different thoughts and what your father thinks is definitely not the same as you, so indeed we just need to make a middle line about what to do regardless of whether you believe it or not it may come back to yourself.
