I want to do a distance learning course, do you know Tech?

Hello everyone, I would like to expand my knowledge in the area of Cryptocurrencies and Blockchain. I am currently interested in doing a complementary course and I am looking for an alternative that allows me to study at a distance. Recently, researching on the internet, I have come across Tech Universidad Tecnológica and I find it very interesting and because they have several courses of my interest and I can study comfortably from home and at my own pace. 

I would like to hear from anyone who has studied here at this university and if the knowledge they offer is useful. Thx!
