This comment is peculiar - among technologists, for years the common refrain I’ve heard is “Bitcoin makes no sense but the underlying block chain ideas are very useful”.

Of course the combination of signed transactions, common visible ledgers, introducing computational challenges to forgery, resiliency through consensus (kinda)… all the bits and pieces can be remixed into really interesting ideas.

Bitcoin, I still don’t get. More public, slower, more expensive, no fundamental utility, and still subject to nation-state interference?
