PANews reported on September 18 that according to CoinDesk, with the opening of the Token2049 conference in Singapore, a cryptocurrency YouTuber who called himself "Professor Crypto" claimed to have won the "KOL Awards" Best Content Creator Award. However, after being exposed by well-known investigators such as ZachXBT, the "professor" was found to have created false popularity by purchasing fans and robot interactions, and quickly deleted posts to respond to external criticism. This incident highlights the drawbacks of KOLs (key opinion leaders) in the crypto industry. They charge fees to publish false propaganda, undermine industry trust, and cause widespread doubts.
