In terms of price, BTC isn't actually the coin with the highest of value, there's 42 coin which is expensive than BTC. But btc however is much accepted by merchants and more popular than any other coins or tokens which I don't think there is any coin popular than BTC. I have talked to some BTC investor but they didn't know Ether. A chinese in the neighborhood doesn't even have any idea what NEO is.
I dont think any other crypto can beat bitcoin. Bitcoin is dominant than any other becausw for me it is the most used thats why the it has the highest volume too. And it actually leads to high price as more investor tend to buy the bitcoin.
