The course is quite great! At least I wouldn't be silly when talking about the Bitcoin stuff. However, students like me who don't have any previous knowledge about crypto technologies should first read through the text book.....

This is a very good overview course for Bitcoin and underlying blockchain and crypto technology - along with homework that is difficult enough to force one to think a bit and review your java skills. Appreciated and enjoyed.

Great course!

Lectures start from very basics of bitcoins and cryptocurrencies and step by step move to very deep information.

It is one of the most usefull and interesting course at Coursera.

Thanks a lot for teachers!

This course is somehow old 2014, but completely shows the how the bitcoin works, and in fact how crypto currencies work in general. They have an awesome chapter about anonymity. Extra material weeks are really good.

An excellent introduction to BitCoin and BlockChain but this is very dated now, the field has been moving really fast since it is quite nascent and I feel this course should have been updated atleast once by now.

With how rapidly cryptocurrency technology changes, I think the course should be updated (or at least addendum lectures added where appropriate). But this was quite comprehensive and fantastic for a free course!

I mine ETH for a very small profit, but this course opened my eyes to many of the awesome inner workings of cryptocurrencies. The professors are very well spoken and the content is intuitively structured!

Excellent course! It not only covers the technical part of bitcoin and cryptocurrency, but also contains a lot of very inspiring discussions about its relation to the real world. I learnt so much from it!

Altocin chapters are outdated but covered fundamentals still hold true and once you understand Bitcoin well you stand on solid ground and ready to venture out on your own. I highly recommend the course!

Meaningful course which gives you the brief idea of what Blockchain is. Although when it's 2020 there are more new initiatives in the blockchain and crypto market. Still a good start for amateurs.

A wonderful course with great amount of knowledge. The assignments can be improved a little as the first assignment is some what difficult and can be broken into two assignments some week apart

Very good view of blockchain´s system. I´m an economist, so I hadn´t any studies about some technical concepts but this course has been very useful to understand how Bitcoin protocol works.

Very good course - I finally fully understand how bitcoins work!

It would be nice to see this course updated with the recent developments in cryptocurrencies (smart contracts, Ethereum etc.)

Great course, with materials concerning both technical and sociological aspects of blockchain and cryptocurrency.

I think there can be more exercises and programming assgnments for learners.

Very lucid introduction to the Crypto Currencies and Bit coin. Thanks for the extensive elaborations else sometime I might have fallen into trap of trying to mine Bitcoin with my laptop.

I would like to thank all people who contribute to this course. The course answers "all questions" of newcomers. I like its format, it gives both perspective and detail view of domains.

Thank you for the informative course. Would be looking forward for more in this field. Also could you please suggest/elaborate on how this technology will help in derivative space.

Absolutely essential for everyone who wants to know everything about Bitcoin and blockchain. Big shout out to the instructors and dept of the course. Would absolutely recommend!

Muito interessante, poderia explicar melhor como funciona a implementação ao menos nos primeiros codigos. Levei um bom tempo para intender, mas ainda não consegui implementar.

One of the best courses I have had! Great for understanding the technical aspects, as well as the economics and social implications of blockchain technologies. Thanks a lot!

Great introduction to cryptocurrency technologies. Complete overview of the what the individual components are and how they work together. Good pace and engaging presenters.

Difficult coding, but the content is well put together and very informative when increasing the depth of understanding of cryptocurrencies in general. Thanks so much!

Good course to learn cryptocurrency basics and know about Bitcoin and blockchain basics..

The programming assignments were challenging and helped with coding skills.

The best course anyone can get on cryptocurrencies. Just follow the videos, don't have to read any book. The course design is perfect, right content in right size.

This course is very interesting, I learned a lot of thing about bitcoin ecosystem and technology behind them. The programming assignment is challenging. Thank you.
