Multisig does it make sense?

I built a 2-of-3 multisig wallet. Did everything right. Felt like a genius.

Then I made the mistake most people make. I didn't test it.

Years later I opened the wallet. Had my keys. Had 2 of the 3. Entered everything correctly.

Zero balance.

The keys were right. The setup was right. But the wallet software had silently changed something underneath me — the derivation path. Your seed creates addresses using a hidden "address map". When the wallet updated, it started looking at a different map.

My coins were still there. The wallet just couldn't see them anymore. Right key. Wrong door.

I got lucky — I had saved the old path and recovered everything. Most people wouldn't have.

Now Morgan Stanley wants to "help" by holding your Bitcoin for you. Custody, trading, lending — the full package.

Translation: they want your keys.

If you're serious about self-custody, multisig is the real move. But if you set it up wrong and don't maintain it, it's just a more complicated way to lose your Bitcoin.

I put together 6 rules that would have saved me from that panic. Plus when multisig actually makes sense vs a strong single-sig setup.

Please let me know if you want the 6 rules.
