Writing Book About Blockchain, Need help!

[Robust Crypto]

Hello everyone!

I decided to write a book about money, Blockchain and Cryptocurrency in my native language.

I want to educate the average Joes in my country, because I think Blockchain can help my country's economy.

So, I'm looking for people who want to share their thoughts.

Will cryptocurrency replace fiat? Why?
Why is the fiat currency flawed?
What problems can the Blockchain solve? Specific ones.
What tricks & tips would you give to a beginner investor in the crypto currency space?

I appreciate every single comment!
