Any user who created a wallet during a specific timeframe was generating insecure addresses. This made the funds very easy to steal.&#xA;&#xA;~1000 BTC were stolen, but some were returned. How?!&#xA;&#xA;White hat legend, Johoe, is how.&#xA;&#xA;He posted about it on BitcoinTalk: https://bitcointalk.org/index.php?topic=581411.0&#xA;&#xA;He would go on to &#34;steal&#34; funds before the hacker(s) could take all of them, and he returned them to Blockchain. We obviously paid him a bounty.&#xA;&#xA;We were able to make up the difference and pay everyone back who was affected by this. Who ended up having to figure all that out?&#xA;&#xA;Me.&#xA;&#xA;I had to go through each individual case, use a complicated method to make sure I was refunding funds to the actual person who lost them, and then send the funds.&#xA;&#xA;Yes, I was given hundreds of Bitcoin and spent the next few weeks distributing them to the people impacted by this entropy issue.&#xA;&#xA;I still have nightmares. The burden of responsibility weighed heavily on me at the time. I was so stressed about screwing something up, triple and quadruple checking everything before moving on to the next step.&#xA;&#xA;This Coldcard situation is many magnitudes worse.&#xA;&#xA;I feel for those immediately impacted by this - the ones who lost their funds.&#xA;&#xA;The hardest part of working customer service at an early bitcoin hot wallet was explaining how Bitcoin transactions couldn&#39;t be reversed, and any lost funds were gone forever.&#xA;&#xA;I also feel for everyone at Coinkite.&#xA;&#xA;It&#39;s easy to hate them right now, but those guys are true Bitcoiners. A lot of them didn&#39;t need to keep working, and may very well vanish from the space after this. It sucks.&#xA;&#xA;Why risk your reputation and everything you&#39;ve built if one little mistake in 5 year old code can ruin you?&#xA;&#xA;Why keep building when you can retire and enjoy life on a beach somewhere?&#xA;&#xA;I suspect many are thinking this very thought right now.&#xA;&#xA;Can&#39;t say I blame them.</html></oembed>
