Company broadens leadership with another appointment to its to Crypto Advisory Board - DogeOS CEO and MyDoge Leader Jordan Jefferson

LOS ANGELES, Sept. 18, 2025 /PRNewswire/ -- Thumzup Media Corporation ( TZUP ) ("Thumzup" or the "Company") today announced its inaugural open-market acquisition of Dogecoin (DOGE), securing approximately 7.5 million tokens valued at roughly $2 million, at a weighted average price of $0.2665. This strategic addition of DOGE to its treasury coincides with the expected launch of the first Dogecoin (DOGE) exchange-traded funds (ETFs), widely regarded as a pivotal development that could accelerate mainstream and institutional investor adoption.

"Dogecoin's increasing recognition, supported by the expected launch of DOGE ETFs, is a transformative moment for the entire digital asset landscape," said Robert Steele, Chief Executive Officer of Thumzup. "Our recent Dogecoin accumulation, combined with our mining initiatives and treasury strategy, reinforces our commitment to supporting Dogecoin's evolution as both a community currency and a productive digital asset."

Building on this momentum, Thumzup is increasing its Dogecoin ecosystem involvement through its proposed acquisition of DogeHash, a cutting-edge Dogecoin mining operation boasting 2,500 advanced mining rigs, with an additional 1,000 units on order, which are expected to be installed later this year. This expansion follows Thumzup's successful $50 million common stock offering in August 2025, priced at $10 per share, earmarked for cryptocurrency accumulation and the procurement of high-performance DOGE mining rigs.

Thumzup is also strengthening its leadership team, highlighted by the recent appointments of DogeOS CEO and MyDoge Leader Jodan Jefferson and Alex Hoffman, Head of Ecosystem at DogeOS, to its Crypto Advisory Board. Jefferson and Hoffman's expertise in blockchain ecosystems should help guide Thumzup's strategic direction in the rapidly evolving cryptocurrency market.
