Competitive video gaming community E-Sports Entertainment Association secretly updated its client software with Bitcoin-mining code that tapped players’ computers to mint more than $3,600 worth of the digital currency. The admission by co-founder and league administrator Eric lpkane Thunberg came amid complaints from users that their ESEA-supplied software was generating antivirus warnings, computer crashes, and other problems. ESEA has published a post titled “Bitcoin Fiasco” that apologizes to users and attempts to explain how the secret code was added.”]
