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?
Yes, Bitcoin will make Altcoins useless as currency for spending but in talking of investment i say no. This is because Bitcoin was not usually use for spending due to not all establishments will accept Bitcoin but in talking of investments, Altcoins have already gained reputation and lot of ICO are become successful because their investment gained so much earnings and that is why many new ICO are keep coming in the market to follow the path of these successful Altcoins.
