You've made an excellent post 
The internet is an important issue regarding the proper adoption of cryptocurrency, but we also need to mention the constant and sometimes inhumane power outages due to regular failures of the electrical system (this goes logically beforehand the internet issue), which also leads to not having any other basic service, such as fluid water... And this, of course, leans much more towards a health issue than economics.
It should also be put on the table that many people have their minds focused mainly on surviving rather than learning how to use markdown to get some write stuff and get coins, or simply learning what a cryptocurrency is, or if it is good or fraud in general, most Venezuelans ignore cryptocurrency simply because they have not had the opportunity to learn about it because most of the people still there have their mind somewhere else they consider more important, and sometimes are.
And something else, cryptocurrencies are volatile, we all know that, well, most Venezuelans are not willing to risk losing -sometimes- the little they have "playing digital currencies", that's a reality.
As Venezuelans, we all hope everything changes soon but man our country is already deep down the void that gets larger and larger... Our issues are not just economical or political anymore, now we have a serious social and cultural matter to deal with for at least 20 years ahead, something that does not really get fixed with tangible things but with the will, something harder to find than coins.
