Bitcoin originates from a concrete customer experience issue: lack of digital money with some cash like properties (non reversible, pseudonymous, trustless, etc). [1]

Something like that had been tried to create a few times before, but Blockchain was the first solution to that problem. In other words bitcoin solved a problem looking for a solution, not the other way around.

That being said, crypto UX has a LOT to improve. But let's not confuse projects that use "blockchain" because some manager thought it was cool, or literal cashgrabs, with actual crypto projects.

[1] You may think those properties aren't good or useful, but there clearly was and is people that find that useful, so let's not beat the dead horse with that debate.
