Billy Markus, the creator of Dogecoin, has recently started following @DOGE_Exchange on Twitter. This move has sparked enthusiasm among Dogecoin enthusiasts, highlighting the emergence of DOGE.Exchange as the leading Dogecoin-focused company dedicated to the popular cryptocurrency, DOGE. Markus' endorsement carries considerable weight, given his influential role in creating Dogecoin and ongoing involvement in crypto. DOGE.Exchange is the only Dogecoin-focused company that Markus is currently following on Twitter. Other companies like TheDogeCard and MyDogeWallet have yet to be followed by the Dogecoin creator, Billy Markus.
