Well with all things you have to start somewhere.  If you are currently unemployed and dream of working at home, then you can really do anything you set your mind to.  Try to break down cryptocurrency into sections and work on broad strokes first then branch out into more specifics as time passes.  I would kind of look at it in these areas as a checklist.

1) What is a cryptocurrency and what is it used for?
2) Specifics of blockchain and what it does and why and how it disrupts things.
3) How do you obtain cryptocurrency, store it, and what can you do with it?  What are the limitations of each type.
4) Difference between types of cryptocurrencies.. Commodities, privacy coins, smart contracts, dApps, etc. and what each class of crypto does.
5) (More specific to this task)  Why does this job pay in Cryptocurrency and whats the advantage (is it borderless?  Is it because they promote international workers and don't want to work with different types of fiat, etc)
6) Specifics of job (checking out specific tasks that are common for these tasks and breaking down the knowledge walls that are in your way.

Basically any task most people are capable of, but are you willing to put in the time to make it happen?  Its hard to bridge a gap between beginner and enough confidence to sell yourself as being capable when it comes to a job.  If out of work and looking, devote as much time as possible to developing skills. Consume yourself with the technology, the people in this technology, and the opportunities within them.  It may take you a whole year to bridge that gap in extreme time constraints but you will get there if you work on it a bit each day.
