I'd say bitcoin is continuing to fail as a currency. It's too cumbersome to use because no one can keep their private key hidden when using the bitcoin core.

But then again, physical wallets that secure the private key despite any kind of malware counteract that.

Despite that, it's far too easy to mis-send bitcoin and have it lost forever because of the cumbersomeness of the public key.

That said, I believe bitcoin and its community devs are addressing all of these issues as time goes on. Bitcoin may be failing now as a currency, but in a few years it should be more public-friendly
