"Now price it in bananas"
As Bitcoin outpaces altcoins en masse this month, the pain has been especially intense for Dogecoin investors after months of public campaigning by both Cuban and others, including the world's richest man, Elon Musk.
Nothing has been able to reverse the meme-based cryptocurrency's fortunes, however, and now, frustrated commentators are even demanding an explanation.
Cuban was in line for retribution this week, with podcast host Preston Pysh suggesting that his touting of Dogecoin on U.S. national television at the highs had been — to say the least — misguided.
Fellow pundit Peter McCormack joined calls for Cuban to comment on the situation against the latter's backdrop of criticism of Bitcoin.
Twitter users further evoked Cuban's claim that he would rather own bananas than BTC, poking fun at Dogecoin's declining purchasing power when measured in the fruit.
In August, Cuban stated that he owned less than $500 of DOGE.
Has the DOGE had its day?
Musk, meanwhile, has moved on to incorporate Dogecoin spin-off cryptocurrencies in his publicity efforts, these likewise seeing huge gains on the back of even the most innocuous comments.
One such coin, Shiba Inu (SHIB), has since seen substantial selling from large-volume investors known as whales.
The Tesla CEO did not escape the wrath of Bitcoiners earlier this year, however, with his Dogecoin activities being met with claims of investor manipulation.
