*  Dont fix whats not Broken * Do BTC and LTC have some flaws, yes, but they are widely out there and have practical uses.

 Can new coins fix these flaws, yes... but then they will have flaws, then another coin will replace that one, and another replace that one...

 There is going to be a never-ending flow of new ideas coming in to implement into a coin, it will never stop. So, most people dont stop to think about this long enough.... Thats why I say BTC and LTC.
