Re: Tutorial website for blockchain

There should be courses like that, search for them. I’m currently taking the following courses - https://www.education-ecosystem.com/arnoud/Ry5WE-machine-learning-wolfram-language.
There’re a lot of popular topics to study, it makes sense to pay attention to this platform.

Is it paid or are there any free courses? The price isn’t important for me, I’m focused on the quality, but anyway.

The courses are free because the platform is based on blockchain. The authors get cryptocurrency as a reward for their work. I also recommend you to consider the following courses, they are very popular right now and are rated high. (How to Build Advanced Cryptocurrency Trading Bot in Node.js - Education Ecosystem (education-ecosystem.com))

I took a closer look at the platform, it seems to be not very convenient and the courses look doubtful. It seems they offer the same level of quality as YouTube courses.

LEDU rewards only for high-quality courses. All published content is checked by other users who are also rewarded. The authors are mainly professionals.
