I personally think hybrid dpos type systems are the best out there at present that have actually been run and tested beyond "testnets".

If one looks at why dpos was created, it becomes painfully apparent why hashrate does not equal price of bitcoin. Bitcoin is wonderful, but needs to change or die imho...

Dont get me wrong, I love bitcoin but just because i love her doesnt mean she doesnt have to look at always pursuing self improvement. :P
