Another month. Another cycle of noise. Self-custody is still the answer. And bitcoin is still bitcoin. Conviction compounds. Q2 starts tomorrow. Stay sovereign.

We didn't build Chain Code Delegation to keep it. We built it as an open bitcoin improvement proposal so any wallet can implement it. Privacy in collaborative multisig should be the standard.

"We know there’s not one right way to self-custody. And for some people, seed phrases still make sense. But if bitcoin is going to be the money of the future, it needs to fit into the lives of the people who will use it." That's why we built Bitkey. https://bitkey.build/beyond-the-seed-phrase-why-we-built-bitkey/
