Coinbase CEO Brian Armstrong faced questioning from Twitter co-founder Jack Dorsey over his alleged disregard for Bitcoin's lightning network, a layer-2 scaling solution designed to make BTC easier to spend. Armstrong claimed that the next step for crypto was to make payments "instant and free globally" through collective work on layer 2 solutions and user onboarding. While Armstrong did not respond to Dorsey directly,

Solana Labs co-founder Anatoly Yakovenko argued that USDC on Solana was cheaper and faster than Bitcoin and lightning and was the currency that people wanted to use globally. The adoption of Bitcoin's lightning network continues to grow over time, with companies like Binance integrating it as a solution for future base-layer fee spikes.
