Hello @blockchainfo friend, best regards from Venezuel.
I barely have a year and a half within this platform and little by little I am learning more and more and with this type of reading and its different interactions with other users I continue to learn from their comments.
definitely cryptos have a future and I share what Andrea says, I would particularly like to be able to pay everything with digital currencies, however in my country that is limited.
Regarding the layers to which they interact, I must say that I am trying to understand the explanation better, so I must investigate about it since it caused me much more curiosity.
Your friend Jose lanz
Hello, thank you for your comment. Enjoy crypto land :)
