Why are you measuring a specific cryptocurrency vs. the whole Internet? The correct comparison for the Internet would be "all cryptocurrencies."

Bitcoin "regressed" (really, specialized) because it got so big that it became speculators' favorite, which made it too expensive for anyone but speculators to interact with. Then, other cryptocurrencies that aren't so expensive to move around were created, and people who wanted to use cryptocurrency as a medium of exchange moved to using those instead. So now the ecosystem supports two applications (investment, exchange) using different tools specialized to those purposes, each better at that thing than a single cryptocurrency trying to "do it all" would be.

Which is, y'know, also the story of the Internet.
