To be honest, I think the bitcoin ETF is the most boring thing about bitcoin right now. Whenever I get asked about it I'm like, "meh".
Yes, the ETF should be good for price and liquidity, since it gives large pools of walled-garden capital more access to bitcoin exposure.
But in my view, the most important thing about bitcoin right now is all of the little hubs popping up around the world. Bitcoin Beach, Bitcoin Lake, Bitcoin Jungle, Bitcoin Ekasi, Africa Bitcoin Conference, Indonesia Bitcoin Conference, etc. As well wallets and other technologies that help them localize their custody of bitcoin rather than keep it all stashed in the giant Binance honeypot or wherever, and any solutions that help link to them all together for payments or that help them trade peer to peer or onboard from fiat to bitcoin in distributed ways.
The rise and connectivity of those hubs is impressive and is worth supporting.
