It is Obvious there is more useful coin now, and most people prefer accepting Bitcoin when you give them option what coin they accept. The altcoin exchange is a playground for speculators, and I'm surprised Bitcoin still has such high % of the total market cap when there are hundreds of altcoins and their market cap is so much higher than their real coin usage would suggest - but it is how market cap works, pretty inaccurate measurement of coin usability. Obviously, bitcoin has no competition in popularity nor price on.
