Crazy Frog — remember him? The ringtone-era celebrity, whose “Axel F” was an early viral hit, has returned. And, as all crazy frogs do nowadays, he’s gotten involved with cryptocurrency. A few days ago, the team behind Crazy Frog kicked off the animated character’s grand comeback with a new single (a remix of Run-DMC’s “It’s Tricky“) and an NFT collection. That NFT collection did not go over well with those out there on the internet who thought that Crazy Frog’s return was only to sell some crypto cash, and Crazy Frog received some death threats.
