Ardor will explode in December cause it will be launched and it will solve many problems like blockchain scalability, child chain transations and will launch the out of the box blockchain creation tool to make easy to everyone to make your own blockchain.


XMR is a good choice they will launch new features, Dash in the way to release new features too is a good choice. Komodo is an implementation of child chains using zcash protocol made by the well know jl777 (good to keep  the eyes on this project). If BU or Segwit  is not implemented than maybe Litecoin can take the throne.
