We probably have multiple alts that one could consider as better version of bitcoin but as you're noticing, bitcoin is gaining more popularity and a fast growth. The price is not a measure of a coin success so what I'm referring to here is the the number of ATMs, exchanges, stores, services, and people accepting it.
So even If we have some people using alts currently because they believe they are better then bitcoin (which may be true), bitcoin is evolving and the development is super active and exciting times are coming. I honestly believe that this make alts useless (say, by the end of the year), your thoughts?
I completely agree with you. A lot of coins will be made completely useless with time, because they will eventually lose the edge they have over bitcoin. The coin that will lose more will probably be bcash. Although they still have better fees right now, that is not doing them any good, since I don't see any major adoption of bcash as a payment method. People are buying crypto to trade, or to save as a store of value, so the fees and transaction speed act more as a small annoyance, rather that the real tie breaker feature.
Also, as soon as bitcoin get the lightning network, it will completely outperform bcash, and the majority of other coins that want to play a role as a payment method.
I think that the only coins that will survive, are the ones that are no directly competing with bitcoin (like ethereum for example).
