Is Bitcoin 'hemorrhaging market share'?  I hadn't heard.  Whatever the case, losing a lot of the users is a fairly desirable thing to me.  Users who want to use a very powerful technology such as Bitcoin to buy their morning coffee are a distinct liability to the system and are in the process of killing it right now (hence this thread.)

No alt I've seen targets the only use-case that I care deeply about nor seeks to address the main problem that Bitcoin has: too many idiot users.  The reason most alts don't have capacity problems is because they don't have users rather than any particular architectural design that they did right.  That is my sense since I've really not studied any of the alts very closely.  I liked some of the ideas in Litecoin when it first came out, but it was basically a regression from Bitcoin in the ways which were important to me.

In spite of it's rather severe design faults Bitcoin is still the leading contender as a reserve and balancing currency on the basis of it's first mover advantage alone, though it is also still better tuned for this duty than a lot of the alts.  Eventually a solution will emerge that makes use of the very powerful method of one simple layer of abstraction (main chain supporting many tuned, targeted, and non-critical subordinate chains.)  I hope it turns out to be Bitcoin which takes on this role and the core devs who organized under Blockstream seem to be thinking the same thing.  It's probably Bitcoin's only real chance of survival as a robust monetary solution which is independent of government control, and falling into that trap will ultimately kill off Bitcoin's value more than making user's pay what it's worth to use the system.
