Satoshi envisioned bitcoin becoming widely adopted as peer-to-peer electronic cash. I think the biggest barrier stopping that from
becoming reality is government regulation, because govts don't like bitcoin competing with their respective local fiat currencies.
But it seems these days that is becoming less and less of an issue, at least in the US.

For example, there is a bill going through Congress to exempt bitcoin payments under $300 from capital gains.

Some US retailers like Newegg.com have been accepting bitcoin for years. I have used bitcoin payments myself to buy computer products
from them since 2022. More recently the Steak N Shake restaurant franchise (founded in 1934) started accepting bitcoin
in all 400 of their US locations. Coinbase has a debit card you can use to pay for stuff with your bitcoin from anywhere that accepts
a regular debit or credit card (I use one myself).



This is my favorite presentation from the Las Vegas conference last month:
