After graduating from Yonsei University's Department of Business Administration, I joined Hyundai Motor Company and spent 10 years doing overseas sales and IT planning all over the world. Meanwhile, I made a big hit with my Bitcoin investment in 2017, and I left the company in 2019 and became a YouTuber. As people's interest in investing increased due to the COVID-19 crisis in 2020, many people naturally became interested in my investment method, and I published several books one after another.

Currently, universities teach students to invest and train future students, and profits earned from YouTube activities are donated to various organizations.
