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?
This simply means that bitcoin is still king. Im not saying that other alts are of no use or less useful than bitcoin. It is still and always the first crypto, so as to say, the alts that can last long are those that have proven itself useful, have real use case and active development team and strong community backing it up.
