The post Vitalik Buterin Warns Quantum Computing Threatens Crypto Security by 2028 appeared on BitcoinEthereumNews.com. Key Points: Vitalik Buterin warns about quantum computing risks. Industry urged to prepare for crypto threats. Expert opinions vary on quantum attack timeline. Ethereum co-founder Vitalik Buterin warned about potential quantum computing threats to cryptographic systems by 2028 at Devconnect, prompting industry debate. This warning highlights urgent concerns over the future security of blockchain technologies, affecting Bitcoin and Ethereum, with the industry urged to prepare for quantum-resistant solutions. Quantum Computing to Disrupt Crypto Security by 2028 At the Devconnect conference, Vitalik Buterin warned that quantum computers might compromise elliptic-curve cryptography by 2028. This foundational security layer is crucial for Ethereum and other digital systems, prompting a plea for the industry to shift towards quantum-resistant technology. His warning aligns with several experts pointing out the imminent risk quantum computing poses to Bitcoin and other digital assets. The industry’s immediate focus involves transitioning to quantum-resistant cryptography. While quantum computing advancement projections vary, many experts agree with Buterin’s warning, acknowledging a need for cryptographic migration by 2028. “Quantum computers will be able to break elliptic-curve cryptography, the foundational security layer of Ethereum and most modern digital systems, possibly before the 2028 U.S. election…. The time to prepare is now,” said Vitalik Buterin. At the same time, physicists project a smaller quantum capacity, enough to delay massive security breaches but still pose a potential risk over time. Market reactions varied as cryptocurrency analysts and industry figures echoed the potential dangers highlighted by Buterin. For instance, Tom Lee shared related reports to stress the relevance of quantum risks for institutional investors. Meanwhile, some firms are proactively responding by accelerating the development of quantum-resistant modules and technologies. Crypto Markets React to Quantum Risk Projections Did you know?

Crypto Casino Luck.io Pays Influencers Up to $500K Monthly – But Why?

Crypto casino Luck.io is reportedly paying influencers six figures a month to promote its services, a June 18 X post from popular crypto trader Jordan Fish, aka Cobie, shows. Crypto Influencers Reportedly Earning Six Figures Monthly According to a screenshot of messages between Cobie and an unidentified source embedded in the Wednesday post, the anonymous messenger confirmed that the crypto company pays influencers “around” $500,000 per month to promote the casino. They’re paying extremely well (6 fig per month) pic.twitter.com/AKRVKU9vp4 — Cobie (@cobie) June 18, 2025 However, not everyone was as convinced of the number’s accuracy. “That’s only for Faze Banks probably,” one user replied. “Other influencers are getting $20-40k per month. So, same as other online crypto casinos.” Cobie pushed back on the user’s claims by identifying the messenger as “a crypto person,” going on to state that he knew of “4 other crypto people” earning “above 200k” from Luck.io. Drake’s Massive Stake.com Deal Cobie’s post comes amid growing speculation over celebrity and influencer collaborations with crypto casinos globally. Aubrey Graham, better known as Toronto-based rapper Drake, is reported to make nearly $100 million every year from his partnership with cryptocurrency casino Stake.com. As part of his deal with the Curaçao-based digital casino, the “Nokia” rapper occasionally hosts live-stream gambling sessions for his more than 140 million Instagram followers. Founded by entrepreneurs Ed Craven and Bijan Therani in 2017, the organization allegedly raked in $2.6 billion in 2022. Stake.com has even solidified key partnerships with Alfa Romeo’s F1 team and Liverpool-based Everton Football Club. However, concerns remain over crypto casinos’ legality as a whole , given their massive accessibility and reach online. Earlier this year, Stake was slapped with litigation out of Illinois for supposedly running an illegal online casino stateside while causing “severe harm to vulnerable populations.” “Stake floods social media platforms with slick ads, influencer videos, and flashy visuals, making its games seem safe, fun, and harmless,” the lawsuit claims. “By masking its real-money gambling platform as just another “social casino,” Stake creates exactly the kind of dangerous environment that Illinois gambling laws were designed to stop.”
