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?
You have a good thoughts about what you say but every coin have their uses not by their value but for what their purposes. Alts become useless because only bitcoin is the one coin that become popular but without altcoins there is no trading and without trading we have no other ways to earn bitcoin only by mining and investing by the used of real money.
