There are still great altcoins out there, so I won't judge them completely and in fact, they also had a big contribution to Bitcoin and to the overall crypto market. There's just people who don't like Bitcoin for some reasons and sadly their decisions may not ever change no matter how hard we convince them.
It's true some person don't like Bitcoin, I've met someone who don't like Bitcoin but after he understood the entire principle of Bitcoin price movement and the concert of limited supply, he became a lover of Bitcoin. I think most of those persons who don't like Bitcoin is because of what they've been told without them carrying out research on Bitcoin network to know what it truly entails, but if such person are given the opportunity to know more about Bitcoin, they'll definitely pick Bitcoin over any other shitcoin or altcoin. While only few just develop hatred for the project. But Bitcoin remains the best coin ever.
