If we can't fix it why would any other coin?
because fixing bitcoin is like changing wheels on a train while it's still working the express route every day.
if nothing else it's providing truly huge amounts of information for other people to take and run with. maybe someone will scratch build something that addresses the most common gripes in a way that's so logical it's impossible to take any type of position against.
a long shot of course, but i wouldn't underestimate the lessons we're learning every day and they're really, really hard to retrofit on bitcoin itself.
