Here, I will also mention Cardano and OmiseGO. These are very good platforms that have a great future. I suppose one-fifth of the altcoins that exist on the market now can survive. Ontology is among them as well.
I shared your opinion, thats why I have solid chunk of my portfolio in OMG, but so far its worst performing coin in my portfolio (CHT been the best)
However, another bull run could totally change that, as CHT is designed to be slow but reliable performer, while OMG could explode again
