New? Start here...
If you're new to this space, here is a great place to get started...
1. If you haven't not yet, you have to read Satoshi Nakamoto's Bitcoin white paper:
It is a must read.
2. Understand what Ethereum actually is, as it is critical to understand the differences between Bitcoin and Ethereum whether you invest or not. https://www.youtube.com/watch?v=U_LK0t_qaPo
This video should show you that the people working on this are doing a lot more than giving birth to a currency. For Ethereum, that is a corollary - not the purpose. If intrigued by this, start reading and listening to Ethereum inventor Vitalik Buterin.
3. Most importantly, you need to at least scratch the surface of Crypto-Economics.
It is not until you get to this point that you will realize what it really going on in this space.
(Note: Vitalik gives the hour long talk re crypto-economics embedded in this story. After getting past the fact that he is just one of the smartest people on the planet, listen to the problems he is actually solving.)
