Dogecoin co-founder Billy Markus (known as Shibetoshi Nakamoto on X) posted "are we back?" coinciding with a general crypto market rally where most cryptocurrencies saw price increases, with some achieving double-digit gains. The tweet provided no additional context, leading to market speculation on whether he was commenting on the overall market conditions, Dogecoin, or broader digital currency sentiment. Bitcoin rose 5% in the last 24 hours, Ethereum gained almost 6%, and Dogecoin increased by nearly 4%.
