I did the same, for example, to create a Wordpress website, and I had to google many times a day, even though now you can find courses revealing all the aspects within half an hour.
I agree, but there’re plenty of videos about how to use Wordpress on YouTube
TBH, the youtube videos are not explaining all of the things. I have been still learning about the programming and i know that we can get a lot of videos from youtube but it's not explaining all of the things so well.
Back to the topic if the learning course has nothing to do with blockchain until it was learning about the crypto sphere.
There are lots of coins that can be used an alternative payment system to the online learning course and block chain is not needed in this case.
