Cool...I think I'd assess your view of BTC as sunny:) Now for some shadow: it was created much like fiat in secret; similarly to fiat, it has a controlling elite dumbly known as whales in the cryptosphere; it's an incredibly fragile foundation for a worldwide economy (one EMP pulse and there is worldwide chaos on an unprecedented scale); it eats up enormous amounts of energy.
Also, and this is just my personal view. My preference would be to have the means of exchange (currency) not be a commodity and store of value (so it can't be hoarded), and that a new currency would have absolutely zero debt mechanisms associated with it.
Cheers!
