So much crypto activity happened yesterday, and here’s a look at the big stories. 

Tokenized US  treasuries surge in big crypto activity 

Real-world assets are absolutely on fire right now, especially with tokenized US Treasuries leading the charge as one of the hottest corners of the market. 

We’re talking about a 50x jump in less than two years, thanks to big institutions chasing that sweet on-chain yield.

Fresh numbers from Token Terminal reveal just how wild this crypto activity has gotten: the total market cap for tokenized Treasury products shot up from under $200 million back in January 2024 to nearly $7 billion by late 2025.

It’s a clear sign that more players are jumping into on-chain versions of safe, government-backed debt.

Crypto activity surges in Brazil

Down in Brazil, crypto activity picked up serious steam throughout 2025. Transaction volumes on platforms soared 43% from the year before, and the average user poured in over $1,000, according to a new report from Mercado Bitcoin.

That report, called “Raio-X do Investidor em Ativos Digitais 2025,” pulls data straight from Mercado Bitcoin Latin America’s biggest crypto exchange. It paints a picture of crypto activity shifting away from quick flips and hype toward smarter, long-term strategies, with locals focusing more on building portfolios and managing risks.

But not all the news boosting crypto activity is upbeat

The community took a gut punch when Wyoming Senator Cynthia Lummis announced on December 19 she won’t run again in 2026. She’s been the strongest voice for crypto in Congress, and her exit leaves a huge gap.

The 71-year-old Republican said the nonstop grind of the job wore her down.  She’s the fifth GOP senator bowing out this cycle. Folks in the industry were quick to mourn the loss: Andreessen Horowitz’s Collin McCune said crypto activity owes its progress to her battles on the Hill, while White House crypto czar David Sacks called her an incredible ally and said he’s gutted to see her go.

All in all, from booming tokenized assets to maturing markets in Brazil, crypto activity keeps pushing boundaries even as Washington loses one of its top champions. And that, friends, is a wrap for today.
