MISSING Features or benefits of ALTCOINS

[neofront]

Hi folks,
 I am trying to come up with a list of features/benefits that are missing in altcoins or non-altcoins.  I'm interested in all opinions.  It can be anything from a security feature to a convenience feature which you feel is missing in ANY altcoin.  I want to hear complaints or compliments.  Anything at all you would do or suggest to make your favorite coin a better coin in the future.  What have you thought of that would improve the security or benefits?  Do you worry about quantum security?  What about blockchain size if a coin was to go "mainstream"?  Tell me what you think!

I wouldn't suggest you to reinvent just another coin. There are realy too much such coins, and most of them will die shortly. You can implement something useful, like project with useful functionality,  where you coins will be used  for internal payments/user rewards etc.

That's not what I am trying to do.  I'm trying to write a paper on how cryptocurrencies could be improved from their current state to make them more "mainstream" and ultimately become a traditional form of payment.
