Since this Coldcard tumultuous period, I was thinking about options about how one might mitigate said scenario's My first thought was a Bitcoin bank that had two core promises... 1- All funds in my bank's custody will be fully insured without exception 2…

I’m just going to write, this won’t be polished. If you have/use a coldcard MK3 without a passphrase, that wasn’t setup with 100+ dice rolls, you need to move your funds out of that coldcard as soon as possible to safe harbor. If you have/use a coldcard MK4/5/Q…

Normal people double-check the stove is off.

I've verified the same receive address four times and I'm going back for a fifth.

Self-custody comes with a little paranoia. I'll take it.

Here's how to create a simple 12 word bitcoin seed using Seedsigner and dice.

Its filmed in real time with a timer running so you can see the entire process & how long it takes

Do you really think this is too hard, or too much trouble for you to secure…
