The price of Dogecoin has dropped 13% over the last week, and has fallen 6% to just under $0.07 in the last 24 hours alone, as per CoinGecko data. 

The famously volatile meme coin has dipped this week amid speculation over potential changes to the energy-intensive proof-of-work mining model that currently powers the cryptocurrency.

Rumors that Dogecoin will undergo a transition to a more energy-efficient proof-of-stake model—akin to Ethereum’s long-awaited merge in September—are circling again on social media, leading one of Dogecoin’s core developers to deny that any major move is imminent.
