It seems to me there is still no such coin, which could now grow just like the BTC. Although it is very difficult to predict which coin will grow in price by 100 times or more.
Yes, a lot of new coins now are booming and many of them really have a great potentials but you are right i think there will still no coins that can replace bitcoin and beats its current price.
I suppose, with time, people will start to trust the crypto much more. That is why it will be growing. I am sure that the best gainers will be the following altcoins: Ontology, EOS, NEM, NEO, OmiseGO, and Gladius.
