What about coins that use different underlying tech? like IOTA [1] (from what I last read about it). The basic premise, if I remember correctly, is that you pay the "fee" by checking 2 past transactions - thus eliminating the never-ending battle of miners and users. The purpose isn't a currency exactly and more of a tool to exchange data and value.
I agree that the UX of the whole crypto scene is crazy with the bottleneck of keeping your secret in a safe place, but you get some drawbacks I guess.
