Demo, I often suspect that your posts are designed to create discord, but I will give you the benefit of the doubt here (or at least suspend my disbelief for a moment) and just address your stated concern.
No country controls any cryptocurrency...and I find it very hard to believe that you don't already know that.
To put it another way, all people, everywhere, in any country, have essentially equal access to cryptocurrency, provided they have access to the internet.
Now, a crypto like Dash would actually be ideal for real-world, brick-and-mortar, or other person-to-person use, due to both the instant transactions AND the very inexpensive transaction fees imposed by the Dash network. Furthermore, Dash's privacy feature makes it doubly attractive, as it means the citizens of Venezuela (or any other country, for that matter) have some means for keeping their finances safe from the irresponsible out of control printing of fiat, and the subsequent out of control inflation and taxation of that fiat.
