Also an important question: How to get quickly tokens for a ETH test network to be able to do anything. Last time I tried I wasn't successful because all these places where you could get some free tokens didn't work and the only thing possible was to mine them yourself which still took a day or two.

For a test network, can't you just modify the code to give yourself however many coins you want? Why would you need to mine?

The metamask testnet faucet worked for me - https://faucet.metamask.io/

The book "Mastering Bitcoin" really helped me to understand the blockchain and bitcoin properly. It's available free online here~ http://chimera.labs.oreilly.com/books/1234000001802/index.ht... The author is putting out a similar book called "Mastering Ethereum" in February, also through O'Reilly.

This book helped me understand the basics of bitcoin as well. Great read.

I assume OP is referring to the test nets which are already running publicly, not one u would run locally:

I loved Decypher.tv for getting going with Ethereum Smart Contracts as well as other requirements for a complete DApp

Seems expensive, currently $60 USD. Worth it?

Yep. I went through all of them and they are great

This article was on HN a few days ago. “Learn Blockchains by Building One” @van_flymen https://hackernoon.com/learn-blockchains-by-building-one-117...

That's an excellent article. And a very hands-down approach using code examples in Python.
