How do one become an Blockchain Engineer/Developer?

[Captain Corporate]

 I study C# and ASP.NET and on the side do some silly wordpress websites for couple people time to time.

 I think blockchain technology will be making bank soon. I would like to be able to call myself an Expert on Blockchain technology and if a Firm needs someone to do something with Blockchain I would like to apply with confidence.

 Where do I start studying and learning about Blockchain?
