Gold and Bitcoin share many of the same properties of sound money.
No they don't. Gold hasn't been considered "money" for hundreds of years.
If we consider gold ETFs as a "layer 2" solution for gold, then this solves most of these issues and there's not much reason why Bitcoin is significantly better than gold as a store of value.
Bitcoin is decentralized, censorship resistant, secure, fast and global. Gold is none of these things and its ETFs are going to be even more centralized.
There's a lot of hype about how Bitcoin is going to save the world from currency devaluation and the endless money printing from governments.
No it is not and nobody ever said such a thing. You won't find a single line in bitcoin's paper or in Satoshi's posts that suggests that. If someone was telling otherwise they were lying.
The corrupted centralized monetary system is not going to change any time soon, at least not in our lifetimes. Bitcoin offers an exit that all people are free to choose and some do.
Do you feel Bitcoin is overhyped?
Bitcoin is not even hyped to be overhyped. Majority of the world are either unaware of what bitcoin is or are ignoring it.
