YoungHoon Kim, a South Korean person who claims to have the world's highest IQ at 276, has made five bold crypto predictions on X (Twitter), where XRP (XRP) is at the center.
Kim has gained many followers on social media and often writes about Bitcoin (BTC), XRP, and general market trends.
Kim says he is 'Son of XRP'
In several quick posts on X, Kim referred to himself as 'Son of XRP'. He claimed that he 'was born to send XRP to 100 USD' and that 'no one can stop him'. Kim also claimed that 'crypto will soon explode'.
These posts are part of Kim's increasingly aggressive support for XRP. He has previously predicted that the price of XRP could reach 100 USD within five years and he has said that the Ripple token is better than BTC.
As of this writing, the price of XRP is 1.32 USD, which is a decrease of 1.67 % in the last 24 hours. If the XRP price reaches 100 USD, it represents an increase of 7,475 % from the current level.
Kim was not satisfied with XRP. He stated that altseason has arrived “100 %”, predicted that meme-coins would surge first and called BTC “essentially a meme-coin”.
Bold claims meet skepticism
Kim's crypto predictions receive extra attention due to his claimed IQ of 276, which he uses to market himself as the world's smartest person. But many have questioned this claim.
For example, his prediction on January 6 failed, where he forecasted a Bitcoin price of 100,000 USD within 48 hours or by January 8. Instead, BTC dropped from 93,747 USD to 91,099 USD.
His previous crypto predictions have also not been accurate. Kim predicted that XRP would reach a new all-time high by the end of 2025. That has not happened. He also said that BTC would reach 300,000 USD by early 2026, which it has not.
A review by VICE published in July 2025 showed that IQ experts could not reproduce the score of 276 from Kim's test data.
Chris Leek from Mensa called the attempts to calculate 276 “pure nonsense”. The Australian psychometrician Jason Betts estimated that Kim's actual IQ did not exceed 175.
Kim's supporters, such as GIGA Society Professional, have responded that the figure 276 is based on a standard deviation of 24, which corresponds to 210 on the more common SD15 scale. A preprint released in August 2025 was later withdrawn.
