thx, it's more clear :)
I think I said the same thing, writing about a the fact that the market believes exchanges actual USD for Steem (via BTC, currently) because Steem has a "technology that can in the future replace the old one, the one currently used for transaction in national currencies all around the world". But if it is how I write, than Steem is just a financial tool.

Of course, "crypto currency economy" is an expression that can mean different things ;)
