☑ Understand the personal and business applications of Blockchain, Smart Contracts, DApps, and Tokens
☑ Explain Bitcoin and Ethereum to your parents/grandparents/dog
☑ Purchase your own cryptocurrency (if you want, but no pressure otherwise!)
☑ Understand the ins and outs of the culture, concepts, and history behind Bitcoin, Ethereum, and the Blockchain
☑ Formulate conspiracy theories about Satoshi Nakamoto
Do you like learning about fascinating technology? Are you considering investing in Bitcoin or Ethereum? Are tired of wondering what the heck the Blockchain is? Or maybe you'd just like to hold your own in a conversation on cryptocurrencies at the office?
This course is for students who wish to confidently navigate the rapidly evolving world of cryptocurrency, and it's taught by developers who love technology, rather than investors looking to pitch you. Many courses focus on teaching you how to purchase Bitcoin, but very few explain how it works or why it has become so popular.
The course begins with a basic overview of the history, concepts and vocabulary of cryptocurrency: What it is, how to acquire it, how to send and receive it, how it differs from differs from stocks and bonds, and what the heck a miner is. With that foundation, you will be ready to take on cryptocurrency's more advanced concepts: mining, forks, digital signatures, hashing functions, smart contracts, tokens, and distributed applications (DApps).
This structure makes our course suitable for students of all levels. No math or coding experience is necessary.
By the end of this course, you'll have no trouble answering the following questions:
This is not a course designed to pitch Bitcoin, Ethereum, or a token! This is a course taught by developers who love technology, rather than investors looking to pitch you.

I am a beginner to all these bitcoins, block chain and mining concepts. I have heard many people talking about it. So i thought of taking this course to make myself familiar with these concepts. This course has given me the idea of how these works. Both the instructors are very good at explaining the the concepts with some examples and demo. I have really enjoyed this course. Thank you Colt and Kevin
Perfect overview for a Bitcoin and Ethereum technology. The explanations are simple, easy to grasp, well illustrated. Good course to understand the basics.
This is a course for beginners as stated and they do cover a good range of topics, the content is definitely there but the delivery is why I marked it down. For the first half of the course they present material and content in an informal podcast manner which wouldn't necessarily be bad but they act like giggling school girls throughout these parts which is beyond distracting and annoying. I lost my patience and skipped some cringe worthy parts, you can tell they're having fun but I did not. I didn't buy the course to hear them banter I bought the course to learn. What you two find humorous and "hee hee haha" at is inane to me and really distracts and even slows the momentum. I'm not even saying don't be lighthearted or don't include some levity but these guys took it to a whole new level with their distracting giggling nonsensical banter.
great course - really clear instruction especially in the first half or three-quarters of the course. I trailed off a bit at the end, but if you want a solid conceptual understanding of blockchain/crypto, I recommend this course
A superb introduction to the world of cryptocurrencies! If you would ever want to go deeper there is a lot of math waiting for you!
Good course, well structured and done in an understanding way. Sometimes I feel like the course is a bit too simplified. I know it's for all kinds of skill levels, but the RSA part could have been more detailed in my opinion, as sometimes that also makes it easier to understand. One thing that bothered me quite a bit was the very frequent interrupting of one instructor by the other (in both ways). It's a good idea to split the course between two instructors, but maybe it might be better to split the roles better or really have one teacher per course, changing between courses. Still reccomend!
Very good! I tried several cryptocurrencies courses, but this one explains how the bitcoin "machine" works in a detailed and easy way. Thank you very much!!
The instructors are well informed, and they explain the content in a fun, interactive way. Enjoyed the course.
I love this course. I've been wanting to learn more about blockchain (the technology aspect - not trading) and this course was SO helpful. The course dug into how mining actually works, how a blockchain remains secure and how individual transactions use public / private key cryptography to keep secure. Definitely recommend!
This is a wonderful course for learning fundamentals of bitcoin/ethereum blockchain. It is also a detailed course and with lots of activities which can help students to grasp blockchain topics easily.
Good overview of concepts and terminology. Not very technically deep (that's not the point) but laying a good foundation for deeper courses.
Minus half a star because they joked so frequently, it distracts me, makes me laugh so hard that I have to rewind it.
The information is there, but the editing/commentary could be cleaned up for better delivery of the information.
This is a decent course to get a from-nothing introduction to how Bitcoin/Ethereum/other cryptocurrencies & blockchain work. But it is entirely theoretical, there is no practical usage of the material being presented. So overall I don't really find it particularly useful, and I would say it is hands down the worst course by Colt Steele here on Udemy.
As someone new to the world of cryptocurrencies, the course had the right amount of high level overview as well as detail.
