Coinbase Mortgages, Privacy for AI and Payments, Lexe Launches

— Coinbase's Bitcoin-backed mortgage product enables down payments using Bitcoin collateral at 40% loan-to-value, with government backing through Fannie Mae and protection against margin calls.

— The mortgage product targets Bitcoin holders who want portfolio exposure without selling; it applies only to conforming loans and uses Bitcoin exclusively (not other cryptocurrencies).

— Lexe's public launch provides self-custodial Lightning wallets using trusted execution environments (Intel SGX) to run nodes in the cloud while keeping users in control of private keys via Google Drive backup.

— Privacy concerns plague stablecoin payments on Base and Stripe; Tempo; normal users expect banking-level privacy, not public blockchain visibility of all transactions and balances.

— Hong Kong's new law allows authorities to compel decryption of wallets and apps, effectively ending financial privacy and making the jurisdiction risky for Bitcoin and crypto users.

— Open source value is shifting from code to data provenance, model weights, evals, and protocols; Spiral is exploring low-level infrastructure projects (peer-to-peer training networks, interpretability, Bitcoin-timestamped model provenance) that won't be commoditized by big labs.

— If you hold significant Bitcoin and are buying a home, Coinbase's mortgage product offers a way to avoid capital gains taxes on the sale while maintaining upside exposure; compare against traditional lending rates and down payment requirements before committing.

— Evaluate Lightning wallets (Lexe, Phoenix, Cash App) for everyday payments; Lightning's privacy properties are superior to Base or Tempo stablecoins, where your transaction history and balance are publicly visible unless privacy features are added.

— Monitor regulatory clarity on stablecoin yields and de minimis tax treatment for Bitcoin payments; Block and Coinbase are pushing for policy changes this year, which could unlock mass adoption of Bitcoin as a payment medium.
