My crypto beliefs:

Bitcoin is good. 

Ethereum is good. 

Solana is good.

Stablecoins are good.

Regulatory and infra are no longer major blockers.

Major blocker is lack of apps. Need more apps.

What's one app you're surprised hasn't been built yet?

The easiest one should be an infra that will take care of international card payment issues.
A crypto card that is accepted in every continent.

This will not only address the hassle of changing money in every country, it will also help onboard many persons (travellers)
