Today in crypto, Jameson Lopp and five co-authors have proposed a new Bitcoin Improvement Proposal that looks to freeze dormant Bitcoin, including Satoshi’s stash. Challengers are taking aim at prediction markets with Crypto.com entering via a tie-up with High Roller Technologies and European stock exchange operator Deutsche Börse said it will invest $200 million in Kraken’s parent company for a 1.5% stake.
Bitcoiners propose freezing quantum-vulnerable coins in BIP-361
Cypherpunk Jameson Lopp and five co-authors from the Bitcoin quantum security space have proposed freezing quantum-vulnerable coins on the Bitcoin network, including Satoshi’s $74 billion stash, to prevent them from being stolen once quantum computers become available.
The move is the second part of a three-stage proposal under BIP-361 called the “Post Quantum Migration and Legacy Signature Sunset,” which was posted as a draft to GitHub on Tuesday.
It addresses a major risk to Bitcoin — the potential use of quantum computers to steal roughly 1.7 million BTC locked in early P2PK addresses, including Satoshi’s stash, which are not quantum-proof.
In the wrong hands, these coins could significantly undermine the value of the network.
Crypto.com gets into prediction markets through High Roller tie-up
Crypto.com has signed a definitive agreement with online casino company High Roller Technologies as part of the cryptocurrency exchange’s move into prediction markets in a challenge to companies like Kalshi and Polymarket.
In a Tuesday notice, High Roller said the deal with Crypto.com would allow the crypto exchange to launch “an event-based prediction markets offering” to US-based users. The notice emphasized that the event contracts would be offered via CDNA, a Commodity Futures Trading Commission (CFTC)-registered exchange, at a time when US state gaming authorities are cracking down on prediction markets.
“We believe this partnership gives us a strong starting position in a market with meaningful long-term potential, and we’re confident in our ability to deliver,” said High Roller CEO Seth Young.
Crypto.com’s move into prediction markets is the latest example of a crypto exchange attempting to enter what couldbecome a $1 trillion market by 2030. Binanceintegrated similar features on its wallet app last week through an arrangement with Predict.fun, a prediction market platform on the BNB Chain.
Deutsche Börse invests $200 million in Kraken parent Payward
Deutsche Börse said Tuesday it will invest $200 million in Payward, the parent company of crypto exchange Kraken, deepening a partnership between the two companies as the German exchange operator expands further into digital assets.
The investment, which is subject to regulatory approval and is expected to close in the second quarter, will give Deutsche Börse a 1.5% fully diluted stake in Kraken through a secondary share purchase.
The investment is another sign of growing interest in the cryptocurrency industry from traditional finance (TradFi) institutions. The deal is part of the Frankfurt-headquartered stock exchange operator’s plans to offer access to a wider array of blockchain-based securities and tokenized investment products and builds on its prior partnership with Kraken.
On Dec. 4, 2025, Deutsche Börse entered into a strategic partnership with Kraken to improve institutional access to regulated crypto investment products like spot trading, tokenized markets and derivatives, including the integration of Kraken-backed xStocks to its digital asset infrastructure, 360X.
Deutsche Börse said the collaboration is intended to produce new products across trading, custody, settlement, collateral management and tokenized assets. A spokesperson for Kraken told Cointelegraph that the deal was based on a secondary transaction involving existing shares and that it builds towards the two companies’ goal to bring crypto and TradFi closer as a “single, cohesive infrastructure for institutional clients,” rather than parallel systems.
