On December 13, Poland reintroduced its Crypto-Asset Markets Law after a prior veto by President Karol Nawrocki, keeping the text unchanged to align with the EU's MiCA framework.

On Friday, several crypto industry groups sent a letter to the SEC opposing Citadel Securities' push to expand oversight of DeFi intermediaries tied to tokenized securities.

Kalshi and Crypto.com unveiled the Coalition for Prediction Markets, bringing in Coinbase, Robinhood and Underdog to press for federal oversight.

Executives say momentum and billions in market activity warrant a unified voice.

On December 12, 2025, Florida Attorney General James Uthmeier announced the seizure of about $1.5 million in cryptocurrency tied to a Citrus County investment fraud, executed under the Fugitive Disentitlement Act.

The move coincides with a push for new crypto ATM safeguards following heavy U.S. losses reported this year.

The Office of the Comptroller of the Currency approved national bank charter applications for BitGo, Fidelity Digital Assets, Paxos Trust Company, Ripple National Trust Bank and First National Digital Currency Bank on Friday.
