The UX for Coinbase app/Smart Wallet + Base + USDC is great now, significantly superior to the incumbent market leaders Binance + Tron + USDT, plus a fraction of the cost. With the Stage 1 upgrade soon, technically it'll be a decisively superior solution (of course, even moreso with Stage 2). Yet, the real solution will be an international network of aggressive business development and marketing onboarding merchants and users from the countries where B/T/T alliance has significant marketshare - Turkey, Argentina, Thailand etc. Breaking these network effects is a very steep battle that requires significant local investment and must not be underestimated.

This is one reason why I think partnering with nonprofits and foundations working to create impact is the next big step (beyond, yknow, being the right thing to do). 

Focusing on impact instead of strict profit or consumer applications will simultaneously get web3 outside the degen bubble and onboard the millions/billions of people who stand to benefit most from this tech.
