Every bad thing has positive aspects just as every good thing also has negative ones.

For now I'm against cryptocurrencies because every plus I've seen is outweighed by the con (pun intended).

And this is actually the second time in a cryptocurrency topic that I ask this and nobody answers.

Let's say I'm in Extremistan or Extremistia. How do I use cryptocurrency? Is it just a store of value? Can I use it for payments?

I want a guide, I'm new to this. How do I use it?
