Hey buddy,

Welcome to the blockchain world.
There are lots of courses: Available courses on Bitcoin and Blockchain Technology from colleges and Universities. In fact, you can find out more online courses, free or paid, from coursera.org or edx.org.

Starting from these ones is good, too.

If you find new cources, which have not yet listed in my thread, you can let know by leaving a post with links to courses you found, I will take a look at them and add them in OP.
