Mark Cuban sold most of his Bitcoin

Mark Cuban He sold most of his Bitcoin holdings Having concluded that it failed to act as a hedge against dollar weakness and geopolitical turmoil, especially during the recent conflict with Iran.

The billionaire investor, who once described Bitcoin as a superior version of gold and maintained a cryptocurrency portfolio heavily weighted in it, said the divergence between gold and Bitcoin during the Iran war was a breaking point. Gold rose while Bitcoin struggled to maintain momentum despite a weaker dollar, which is the exact scenario the “digital gold” thesis was supposed to achieve.

Cuban commented: “I always thought it was a better version of gold than gold, but gold just went up and got to $5,000, and Bitcoin went down. Every time the dollar went down, Bitcoin was supposed to go up. It’s not the hedge I expected.”

His disappointment extends to cryptocurrencies, where he feels he has yet to find a “novelty app.” That includes NFTs, which while he refrained from calling them dead, she said were “disappointing.”

This view is becoming more common, as more holders of 5- to 10-year bonds begin to give up in 2026. Unfortunately, this trend seems more likely to continue rather than reverse, at least in the near term.

A startup says it can rescue Satoshi’s 1.1 million bitcoins from quantum attackers

Researchers at AmericanFortress Posted a proposal They claim that their multi-layered quantum defense system can protect Satoshi Nakamoto’s 1.1 million dormant Bitcoins (and all other currencies) from future quantum attacks via a soft fork that would freeze and protect exposed addresses.

The problem they solve is the “Satoshi problem” that has haunted all quantum defense proposals to date. The approximately 6.9 million Bitcoins held in addresses with exposed public keys are directly vulnerable to any quantum computer powerful enough to run the Shor algorithm against the secp256k1 elliptic curve cipher. BIP-361, authored by Jameson Loeb, proposed freezing those coins if they didn’t move to quantum, but Cardano founder Charles Hoskinson pointed out a fatal flaw: “1.7 million coins can’t do that. It’s not possible. 1.1 million of them belong to Satoshi.” If Satoshi dies or the keys are lost, there is no way to migrate voluntarily.

AmericanFortress’s approach is different. Instead of requiring a migration or enforcing a freeze, their proposal uses a soft fork to create a protected sleep state, essentially placing a quantum-resistant cryptographic lock around vulnerable addresses without requiring the owner to transfer coins or prove control. The system applies multiple layers of post-quantum signature schemes to prevent a quantum attacker from exploiting exposed public keys.

The proposal is in the early stage of peer review and has not been submitted as a formal BIP. A parallel PACTs proposal from Paradigm researcher Dan Robinson offers another path, allowing token holders to stamp cryptographic proofs of ownership today and then unlock the coins later via quantum-resistant STARK proofs if the network freezes vulnerable addresses.
