On January 17, the Block B members guested on MBC FM4U's 'Kim Shin Young's Hope Song at Noon'. During the radio show, DJ Kim Shin Young asked the 'sexy brain' idol Park Kyung, "You're a Mensa member, but what is the dumbest thing you've done recently?"
Park Kyung responded, "I made some extra cash recently so I invested in Bitcoins but failed. I think that is the dumbest thing I've done recently. I regret it and I learned a lot from it."
Hearing this, Kim Shin Young commented, "Saving is the only (right) way to go."
