Cryptocurrency pioneers, nice to meet you, this is my dad's account.
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!
Well hello OP and sorry to hear what has happened to your father. Because of what happened to your father i can also understand that you have a very negative opinion about altcoins. That being said, i totally disagree with you statement that all altcoins are bad and Bitcoin is the only viable crypto project out there. There are quite a few bitcoin maximalists in this forum that would agree with you though.
I think that there are altcoins out there like for example Ethereum or Cosmos that are really offering a lot of utility to it's users and also brought the whole crypto space to a whole different level. Just imagine we would not have Ethereum and it's smart contract functionality.
