Crypto people love to say “it’s the early days.” But it’s not. Bitcoin is 13 years old. At that age, Windows was on >90% of the world’s computers.

Cryptos are used by maybe 0.1% of computer users (if we’re very generous about what exactly constitutes usage). Considering the amount of investment they are an expensive failure…
You're comparing apples to oranges. Decentralized systems by nature suffer for slow adoption (just look at decentralized networks like Mastodon which are objectively better than alternatives yet lag behind in adoption).

We still struggle to adopt centralized systems…
It was pretty damn big after it was 13 years old.
