Steak 'n Shake Says Bitcoin Still Cuts Payment Fees by 50%(reddit.com)
>From article. Traditional card networks often charge merchants various fees. These costs can add up quickly when businesses process large transaction volumes. By accepting Bitcoin, Steak ‘n Shake reports that it reduces those expenses significantly. The company views the lower cost structure as one of the strongest advantages of cryptocurrency transactions. Those savings can improve operational efficiency and potentially strengthen profit margins. submitted by /u/zesushv [link] [Kommentare]
A conversation with a colleague who believes he bought "2 whole Bitcoins"(reddit.com)
A couple of months ago, a colleague proudly told me that he had purchased "2 whole bitcoins" for $80,000 each. I asked him to show them to me so I could see what he had spent $160,000 on. He opened his wallet application and pointed to the screen, which displayed 2 BTC. When he claimed that those were his bitcoins, I disagreed, explaining that he was merely showing me a record, i.e. one symbol, not two of something. To prove my point, I wrote "2 BTC" on a piece of paper, held it up, and joked that I had just created two bitcoins for free. He laughed and objected, arguing that my paper note wasn't Bitcoin. He explained that Bitcoin only exists when a network of computers running the Bitcoin protocol records that someone has 2 BTC. ​I accepted his premise and suggested we break down the entire Bitcoin system to see what we could find. ​So, you have the network of computers, the software, the protocol, the cryptographic keys, and the blockchain records, including his own "2 BTC." Yet, despite accounting for all of it, nothing that could actually be defined as "two bitcoins" was there. I pointed out to him that his purchase was no different from what I had written on the paper for free. At that point, my colleague shifted the argument to fiat currency. He countered that if I had $1,000 in a banking app, he could similarly write "$1,000" on a piece of paper and have exactly the same thing for free. I rejected his comparison and proposed that we examine the banking system the same way we did with Bitcoin. I explained that while we would find computers, software, protocols, and database records showing my 1,000 USD, we would also find the underlying loan contracts that created those records. We would find real borrowers who are legally required to repay those loans. Therefore, what I have is a thousand units of a claim on the future production of bank debtors. I further explained that those debtors must provide actual goods, services, labor, or assets to earn the dollars needed to settle their debts. If they fail to do so, their property is seized and sold at bank auctions to honor the claim. I noted that when he wrote "$1,000" on a piece of paper, he had only created symbols, not a claim on debtors and their property. Conversely, with his "two bitcoins", I had created the exact same thing he has: symbols. He attempted one last pushback, arguing his bitcoins were valid because they required immense energy consumption and strict mathematical rules, whereas my paper note was completely arbitrary. In response, I told him to hold my pen, dropped to the floor, and hammered out 50 strenuous push-ups. Standing back up, I picked up the pen and wrote a strict rule on the paper stating I would never write a number larger than 2 BTC. I explained that those push-ups were my proof of work and that note was my rule. I pointed out that because my energy expenditure was local and my self-imposed protocol was strictly capped right there, my bitcoins were actually scarcer and more exclusive than his. I concluded that modern snake-oil salesmens had convinced him to give up actual claims equivalent in value to four new cars for something that anyone can create instantly with a few strokes of a pen or taps on a keyboard. My colleague then stated that he didn't want to have this conversation anymore. submitted by /u/BinaryLyric [link] [Kommentare]
2026 is on track to be the worst year for crypto hacks ever. AI is a big reason why(reddit.com)
Q2 2026 just set a record: 83 separate crypto hacks, the most ever in a single quarter. over $750 million stolen. april alone was $606 million across just 12 incidents. and we're barely halfway through the year. but the scary part isn't the numbers. it's how the attacks are happening. multiple security firms (TRM Labs, CertiK, Chainalysis) are now saying the same thing: attackers, especially North Korean groups, are using AI to find and exploit vulnerabilities faster than protocols can patch them. here's what that actually looks like in practice: AI-powered vulnerability scanning. attackers are running AI agents that scan smart contracts continuously for exploitable bugs. a protocol's security team might audit their code once or twice. an attacker's AI agent runs 24/7 for weeks, spending $10-20k in compute to find a single crack. the economics are wildly asymmetric: a defender's audit has a budget and a deadline. an attacker's scan has neither. deepfake social engineering. the Zerion hack in april used AI-generated social engineering in a long-term campaign to steal from hot wallets. there are now tools being sold that use voice manipulation and deepfakes specifically to bypass KYC checks on exchanges. this isn't theoretical. it's a service you can subscribe to. automated exploit development. tasks that used to take skilled researchers months, like reverse-engineering contract logic and chaining exploits, can now be done in hours with AI assistance. the barrier to entry for crypto hacking has dropped dramatically. target selection. AI is being used to identify the highest-value targets by scanning TVL, contract complexity, and security posture across hundreds of protocols simultaneously. attackers are picking their targets more intelligently, not just opportunistically. the result: more frequent attacks, more sophisticated execution, and a structural advantage for attackers over defenders. one security researcher put it bluntly: "before AI, the number of elite hackers was limited. now almost anyone could operate like an elite hacker for a subscription fee." the uncomfortable question this raises for defi: most protocols are still running the same security playbook from 2022. periodic audits, bug bounties, maybe a monitoring dashboard. that worked when attackers were humans with limited time. it doesn't work when the attacker is an AI agent that never sleeps and costs almost nothing to run. what actually needs to change? is it just "more audits and bigger bug bounties" or does the entire security model for on-chain protocols need to be rethought from the ground up? submitted by /u/ginete_tech [link] [Kommentare]
"Bitcoin is a pet rock", says the guy whose entire industry runs on COBOL(reddit.com)
Banks been bragging about their ironclad systems while running 60-year-old COBOL spaghetti that no one understands anymore. 95% of ATMs, core financial plumbing, all held together by duct tape, prayers and coke. Anthropic drops Mythos and it speedruns classified systems in hours, not weeks. Warner dropped the quote, Dimon himself admitting AI just exposed a mountain of vulnerabilities. Hey y’all... go check out my pet rock collection. Those rocks don't have technical debt. They don't cry when the next AI red-team rolls up. Imagine calling Bitcoin a pet rock while your industry depends on a programming language from 1959, undocumented workarounds nobody understands, and a COBOL engineer who retired three times but still gets emergency calls on weekends. The same people telling us crypto is a dangerous experiment are quietly praying nobody touches their mainframe because nobody knows why it still works. At least the pet rock don’t require a crisis meeting because someone restarted a server. It doesn't have 40 years of technical debt hidden behind a login screen. Our traditional finance is a haunted archaeological site that somehow processes trillions of dollars a day. TL;DR: The people mocking the pet rocks are running civilization on COBOL spaghetti submitted by /u/FluffyAspie [link] [Kommentare]
Swapping Crypto between two different wallet in Samsung blockchain wallet(reddit.com)
Hey folks, first time crypto buyer. Bought small amount of USDC (16$) via a bitcoin atm so that I can send it to my poker app to play some microstakes. When I tried to send it from my samsung wallet to my poker balance it says I did not have enough eth. After some googling it looks like I need to have some eth as gas fees, my own stupidity I should have checked how that works. I assumed the fee would just take from USDC. My question - does anyone know how to convert some of the USDC to eth? When I try and send it to eth wallet I need eth to cover the fees. If there is no way I will just have to wait until I can get to a bitcoin atm again. Thanks in advance! submitted by /u/Esteagee [link] [Kommentare]
