For that amount of Bitcoin, what else could you think of besides cold storage? Here’s your answer anyway: https://x.com/nayibbukele/status/1768425845163503738?s=46. An extra layer of security is multisig, which you should have noticed earlier from the image LDL shared. That’s the right setup because it’s not a single individual who owns the Bitcoin, it’s a whole country. I believe this is the standard way every country should arrange cold storage, with the signers and their key access kept secret.
