Remember when Chubby Checker basically ruined his reputation by accusing a WebOS app that nobody knew about of ruining his reputation? According to Tweakers, Kanye West is doing something similar: he's suing people involved with the cryptocurrency named Coinye for 'deliberate infringement of trademark and unfair competition'*. The use of Coinye supposedly hurts his reputation every day.
Not that the average person has heard of Coinye, of course; that is, until now.
