Unstoppable code was disproven when they forked after the DAO, and World Computer seemed to be a bit far fetched when I understood what a blockchain is good at.
I bought into the hype, I want to believe we can make the world a better place, similar with why I got into Bitcoin. Back then, there wasn’t as much Bitcoin signal, it was an altcoin world. Also, I remember all traders denominated in btc, that also had a large impact on how i viewed btc vs. altcoins.
In the end it was a matter of simplicity, there was enough to learn about in the Bitcoin ecosystem without needing to learn about 100s of other coins.
