Today in crypto, a new staff paper from the Danish central bank revealed that only 4% of Danish citizens own crypto, far below other European countries, Jameson Lopp and five co-authors have proposed a new Bitcoin Improvement Proposal that looks to freeze dormant Bitcoin, including Satoshi’s stash, and challengers are taking aim at prediction markets with Crypto.com entering via a tie-up with High Roller Technologies.
Only 4% of Danish citizens hold crypto, far below other European countries
Only 4% of Danish citizens own cryptocurrencies, a figure that has remained unchanged since 2023 despite the global growth of the sector across Europe and other jurisdictions, according to a new staff paper from the country’s central bank published Wednesday.
The Danmarks Nationalbank staff paper, based on a survey conducted by Epinion, revealed that among those who do hold crypto, most maintain relatively small positions. The majority reported holdings below 10,000 Danish kroner (around $1,570), with total national holdings estimated between $317 million and $847 million.
The survey is based on responses from 3,013 citizens aged 15 and above. The data was gathered between October and November 2025 through Denmark’s Digital Post system, with options to respond online or by phone. The sample was weighted to reflect national demographics.
The findings show that Denmark sits at the lower end of crypto adoption compared to other European countries, where ownership rates are higher. Countries such as Norway, Finland and the United Kingdom report over 10% of their populations hold crypto assets.
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.
