Crypto analyst Nico Cabrera published a viral open letter on X (Twitter) addressed to Coinbase CEO Brian Armstrong, listing 144 real-world blockchain use cases and urging him to stop blocking the Digital Asset Market Clarity Act (CLARITY Act).
The post gained traction across crypto communities just as Coinbase reportedly rejected the latest Senate stablecoin yield compromise for the second time.
144 Use Cases, 1 Question
Cabrera organized the list across 14 categories, from finance and supply chain to healthcare, education, and government. The thread covers remittances, tokenized bonds, decentralized insurance, digital identity, carbon credits, medical records, and dozens more.
“Dear Brian Armstrong, it’s time to stop. This started back in January with a narrative that made sense — letting people earn with their own money. Respect for that. But now, enough. You’re protecting your business. Fair. But this industry is bigger than Coinbase,” wrote Cabrera.
His argument is direct. Yield represents just one of 144 listed applications. Blocking an entire regulatory framework to protect it, Cabrera wrote, prioritizes one business model over the broader industry.
Cabrera tagged SEC Chair Paul Atkins, White House crypto advisor David Sacks, and Senator Cynthia Lummis, among others.
Lummis warned on March 25 that lawmakers cannot afford to wait until 2030 to pass the bill.
A Bill Stuck on Yield
Coinbase earned $1.35 billion in stablecoin revenue in 2025, roughly 19% of total revenue. The exchange rejected the latest CLARITY Act draft in Senate meetings on March 25, objecting to provisions crafted by Senators Thom Tillis and Angela Alsobrooks that restrict passive stablecoin yield.
This marks the second time the exchange has stalled the legislation. In January, Armstrong pulled Coinbase’s support hours before a scheduled Senate Banking Committee markup. This forced its indefinite postponement.
Senator Bernie Moreno warned that if the CLARITY Act does not pass by May, it risks stalling indefinitely ahead of the 2026 midterms.
Meanwhile, frustration is spilling, with some users calling for a Coinbase boycott after the exchange’s latest rejection.
“Yield is ONE use case. Adapt. Let this move forward. Don’t hold back an entire industry for one business model,” Cabrera concluded.
