Not understanding anything as a beginner. No step-by-step guide to buying and selling as a beginner. I'm just watching it because I paid for it already.

By Chun Lung Tsang on 7/17/2023

This course is well-structured and easy to follow, with clear explanations and examples that help solidify key concepts like what the crypto is behind and how it works. Also, this comprehensive course covers a wide range of topics, from the basics of blockchain and cryptocurrency to more advanced concepts like DeFi and NFTs in only four hours. It's really cool for someone who is interested in crypto but doesn't have any background in programming or wants to know how we actually use crypto.

This is a well-presented course introducing the complex world of crypto and DeFi to a general audience.

The course is very beginner friendly and the course will bring you from zero to hero in 5 hours, with meticulously crafted contents providing fundamental knowledge you need to excel in Web3. Beside teaching the technical details, the instructor emphasised the safety and precaution when interacting with DeFi. This is extremely valuable as it may otherwise be a very expensive lesson. Highly recommend!

By Leo Lau on 3/22/2023

I am really impressed by the instructors on how they explain things from the fundamentals of currency. That is something not other courses will start with. And the ways they explain crypto is really good. When i watched those YouTube videos, i feel like i understand it but i am not. Until i enrolled to this course, i just like being blown away. Everything just suddenly being clear. I will strongly recommend this course to whom it might interested in blockchain technology.
