Unpopular opinion: self custody isn't right for everyone, here's my story.

Strategy's Q2 $8.2B loss confirms the STRC problem we found in our Q2 crypto industry report

STRC launched July 31, 2025 at a 9.00% yield, designed to stay pinned at $100 par. It never really held there. Every time it drifted below par, Strategy's answer was to raise the dividend, 9.00% at launch, up to 11.25% by January, 11.50% by...

BTC is still around $64k, but hashprice is only about $32/PH/day right now. That’s basically what miners earn for each unit of computing power. The June low was around $28. So BTC has recovered a bit, but miner revenue really hasn’t recovered much w...

What is the biggest lesson BTC taught you?

The biggest lesson BTC taught me is that if I plan to hold it for years, the daily chart should not affect my decisions. I still check charts sometimes and adjust the amount I buy based on the price that day, but I'm not to treat every red or gre...

Coinkite (Coldcard) needs to offer a bounty to the hacker/hackers sweeping the funds

Coinkite needs to entice the hacker to become a white hat, by returning the funds in an organized way. If they offered 10% -?% (after costs are deducted) of the value swept back I am pretty sure the hacker/hacker would prefer to avoid the headache o...

ColdCard Headlines

The coming “Bitcoin Hacked” “Is your Bitcoin Safe” “AI Cracks Bitcoin” are going to be obnoxious. This is one company, with an over confident leader whose marketing positioned the ColdCard aura as invincible with the messaging pushed down through th...

Reflection on today's episode

Today's episode literally killed the faith of several hardcore old time bitcoiners and I'm shaken too, not going to lie. Even more than the FTX collapse. Why? The mantra "not your keys, not your coins" was already widely spread out...

Coldcard vulnerability was avoidable if they had required user-input based randomness

I don't know Coldcard but it seems from what I've read of the exploit, it's because they let the computer generate the random seed and not use anything outside the computer's software. This is kind of unimaginable to miss at the first...
