Bitcoin
Monero
Siacoin
Decred
Bitcoin definitely as major coin.
Monero as best anonymous coin so far, and probably will stay on this top for a longer time.
Decred I will watch this one very closely.
1) Ripple / because of its application in banking use
i agree with this , ripple seems have big consortium support and their laboratory
still doing work.
But nothing will change fact that this is centralized platform.Whole idea behind bitcoin was decentralization and escape from economic slavery..Small men can be its own banker..
