I've said it here before, I personally see BTC as the perfect store of wealth and consequently the strongest form of colateral.
All the issues that Charles talks about in that video - giving people a financial identity, enforcing property rights and transactions through smart contracts, etc - that's not BTC. And as Saylor says, NO THANK YOU.
I watch Charles' videos, the guy is smart as fuck and he can communicate. And it's interesting to watch what they're doing with Cardano. I think it is a legit project -- I just don't store my wealth in it, because that's not what Cardano does. And even if it did, BTC would still be better for that.
