If that isn't positive news, I don't know what is.
It's pretty big that someone from the U.S. Commodity Futures Trading Commission believes in the success of cryptocurrencies.
He didn't mention any specific cryptocurrencies and is just using the word blockchain.
Seems like a bit of a cop-out to me.
I agree that it is good news, but again nothing is certain in this world. I also noticed in past years that many are speaking about blockchain, not crypto, but it is logical because some people don't want to favour some particular coin. They like blockchain, and idea of crypto but are waiting to see how will this look like in 5 or 10 years from now.
