Thanks for the hint. I'm interested in developing new coin (start a blockchain) in the main manner, but I think about implementing some new things that makes the blockchain useable for other things than being just a pay-coin. I'll like to start with something most simple like a plain draft coin in a language that doesn't get me too confused for start (like c++ is really complex).

I'll have a look for the book you mentioned and also for RUST language which could be a possible candidate to learn/work with if it isn't too complex and easy to learn by doing.

For anyone else... for RUST/blockchain development this links look like a good start I'm also looking into these:
