Hello @alquimista1501, everything you say in general lines largely reflects the resection sustained over time that my country (Venezuela) continues to live, with the great detail that this country does not learn from the antecedents, or as we say, this is a country with a short memory. .!

And precisely, I too am taking short steps in the world of crytography so that the changes that are to come do not take me by surprise.

Great post friend..!
