Hey there! I'm JohnnyTime, and I absolutely love creating clear content about blockchain security & DeFi. Having 12 years of cybersecurity experience, I've always been passionate about education. What really drives me is the impact it has on people. I enjoy simplifying complex technical concepts and helping my students understand them. The best part? Seeing my students shine and succeed in their journeys!
