I take issues with statements like "The technological dominance of Bitcoin is unrivaled."
How is that the case? Technologically speaking Bitcoin is worse in almost every single account to other cryptocurrencies.
I'm generally on board with the whole argument for CRYPTO taking over the financial world. I've never seen a reasonable argument as to why it has to be Bitcoin.
And yes, the main use for Bitcoin TODAY is speculation. That's it. The only thing it's done better than other cryptos: Go up in price more.
