I'd argue some of the cryptocash ideas thrown around in the 90s were vastly superior on the technical front. We've had the schematics for instantanous, high transaction volume, offline, double-spend resistant, completely untraceable and anonymous, digital cash for 25 years... with no blockchain or energy crazy energy consumption requirements.
Why didn't these technologies succeed? Because none of those properties have any business advantage over boring, simple, centralized credit-card processing and back then everything was sealed up in patents until it missed the boat.
I also like litecoin for the purely selfish reasons of it still being (relatively) cheap. BTC prices are out of my ability to play, and most ICO's are derivatives of 'ScamCoin'. LiteCoin is one of the few options it feels I can still get in on the action with a purpose driven coin with a strong/transparent dev team.
One can argue that Dash is superior for payment. But because of network effects and bitcoin's battle tested security (and utility as store of value or settlement layer) even I as a big (but not fanatic) Dash fan hold more Bitcoin than Dash (BTC 55%, DASH: 21%, EOS:24%) If Dash becomes mainstream, then that 21% of mine will be enough for me. :)
Just curious here: What would you say are technically better solutions than bitcoin?
