BTC has no competition because most of the other cryptos don't possess the neccessary qualities to bring something better than what BTC has.They are just kind of in their own thing but they cannot make a difference on a global level and that is why they can't go to another level.So BTC will most likely be the number one crypto for quite a long time to come,for me the most interesting question is which will be the crypto that will have the chance to surpass BTC and how long will it take
That is all true and its interesting how many other cryptocurrencies appear each day but with no bigger success. And none of this currencies can't come even close to Bitcoin value. The only currency that is kind of small competition to Bitcoin is Monero, but only in sense of anonimity and that is why is used on dark markets and Bitcoin has lost a big deal of its anonimity.
