Question

Cryptocurrency

Until recently, I was not interested in and did not think about such a thing as cryptocurrency.
After the release of stellar, I wanted to learn more about this type of currency, but google search is not very helpful in this, so I appeal to Toster's enlightened audience in this regard.

Answer 1
