Another more course in blockchain material, has certain benefits, I consider it a bit informal, I would say that it is aimed at beginners who individually want to learn about blockchain technology. It is not oriented to companies. In the form of looking a little expensive, but it has a method of refunding the money you pay for the course if you request it within 30 days. I say they are informal courses since they do not issue certification. not available for all countries.
It has a course for people interested in making money on blockchain platforms that offer it. Something interesting right now to earn money from home.
