https://ift.tt/NOPlGCz is a good course to learn about Bitcoin and Blockchain?

I already have a pretty good knowledge about it and things like proof of work, proof of stake, DeFi but I would like to learn more in-details things. I thought about a dev course such as [Althash University](https://ift.tt/G7a50YM), is it a good one? Any comment/advice?!
