History made. @MARA is the only public company to join the 50/50 Club — surpassing 50,000 BTC and 50 EH/s. ✅ 50,000+ bitcoin ✅ 50+ exahash No one else is even close. This is what leadership looks like.
50,000 BTC now in MARA’s treasury. Fueled by 57+ EH/s of computational power, reinforcing new foundations for our nation’s digital economy and energy infrastructure. This is MARA for America in action. Next target: 75 EH/s by year-end.
