I had a bunch of links for the 21.co bitcoin tutorials. It was quite extensive, and I thought I would start working on them for some day. The day has come, but I can't find the material.
They have rebranded the website so it became earn.com and I can't find the tutos anywhere on the web. I guess another good reason to dislike coinbase.
If you have info, or a mirror link, or whatever, I would be grateful.
Edit: The url https://earn.com/learn/ gives a 404 which is a sad thing.
