Hello, I am interested in learning blockchain programming to be part of the development. For simplicity, let's say I want to build a platform whether it is utility coin or cryptocurrency, I want to develop for possible ICO. I understand the concept of blockchain and I've been researching about them, so I know at a high level how it works. As a newbie, I have 2 questions:

1. Where to start learning (Solidity?)
2. What resources are there and what is best? (Any recommendation for books, or e-course, any good learning websites? Youtube follower?)

Any recommendation would be great... Thank you so much in advance.
