Safest Way to Store Bitcoin: Self-Custody or a Custodian?

Coldcard users around the world lost $130M+ of Bitcoin this month, and you’re wondering:

What’s ACTUALLY the safest way to store your Bitcoin?

People have told you self-custody and hardware wallets are the gold standard…

But here’s the truth about handling your $BTC yourself:

It’s never 100% safe.

But what’s the alternative, and is it any safer?

What happened with Coldcard?

Before we go into alternatives, here’s a 30-second recap of what happened with the Coldcard wallet hack:

• July 30: $BTC starts disappearing out of wallets.
• These wallets were supposed to be safe, cold-storage addresses.
• 1,083 $BTC was gone in 41 minutes.
• 1,196 addresses drained.
• Total losses: over $130 million.

And it was obvious something wasn’t right.

Every transaction out of those accounts sent the entire balance, and overpaid the transaction fee at exactly the same rate.

Someone was in a RUSH.

The speed and the pattern made it clear that an automated tool was working through a list of wallets – and it already knew how to break every single one of them.

But the key point is this:

It wasn’t the self-custody users that failed.

The owners didn’t lose their hardware wallets, or leak their seed phrases.

Most of them did everything “right.”
