Eth/Cardano aside, or say what you will about Charles, but I still regularly watch this video from time to time to remember just how far we've come and how far we have yet to go for the unbanked

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.
