For a long time I was proud of being the only key.
No exchange holding my coins. No custodian, no counterparty, no permission needed from anyone. Just me, my seed phrase, and the quiet confidence that nobody could touch what I'd worked for. That's the whole promise of Bitcoin, and I'd actually done it.
What I didn't think about is what that means if I'm gone.
If something happened to me tomorrow, my stack doesn't go to my family. It just stops. The keys are in my head and in places only I know about. There's no customer service line for my wife to call. No password reset. No estate lawyer who can subpoena a company that doesn't exist. The same sovereignty that protects my Bitcoin from everyone else protects it from the people I actually want to have it.
I knew this the whole time. I just didn't deal with it, the same way I didn't structure my early buys right even though I understood DCA better than most. Knowing a thing and acting on it are two different muscles.
What finally got me was a boring afternoon thinking about my wife. If I died tomorrow, she'd be the one left standing in front of a stack she can't reach. We'd talked about Bitcoin plenty, but talking about it and her actually being able to access it are two completely different things. The keys were in my head and in places only I knew about. I'd built a wall nobody could climb and then forgotten to leave her a door.
And it wasn't just her. My mother reads everything I write, uses the tools I build, and she's getting ready to make her first Bitcoin purchase. Watching her get close to taking custody for the first time put it in sharp relief: every single person who holds their own keys eventually runs into this same question, whether they're four years in like me or about to buy their first sats like her. The custody problem and the inheritance problem are the same problem, just seen from different ends.
Here's the uncomfortable truth about self-custody nobody puts on the merch: being your own bank means being your own estate department too. The exchange you left was also doing inheritance, badly, in the background. When you walked away from them you took that job on yourself whether you realized it or not.
The fix isn't complicated, it's just unglamorous. Someone you trust needs to know that Bitcoin exists, where the keys live, and how to reach them if you can't. That's it. The mechanics can be as simple as a sealed letter or as robust as a multisig with a lawyer holding a key. What matters is that the bridge exists before you need it, because the one guarantee is that you won't get to build it after.
I put together the wallet inventory and the executor instructions I'd been avoiding. It took an afternoon. The relief afterward was bigger than I expected, the same kind of calm I felt when I finally shut the miners down and stopped white-knuckling the price. Dealing with the thing you've been avoiding always feels lighter than carrying it.
If you've been the only key for a while and haven't faced this, the inheritance planner I built at satoshitrailblazer.com walks you through the inventory and the executor docs so your stack doesn't die with you. I built it because I needed it myself and kept putting it off. Same conviction, better preparation.
You did the hard part already. You took custody. Don't let that be the thing that loses it.
