in no case. none of the coins currently on the market will be able to circumvent Bitcoin in the market capitalization
I agree, bitcoin has long been in the market and has proven itself very well, and the more the entire market is traded to bitcoin, I also do not think that something will replace it
But the Ether is still much more promising if not even replace Bitcoin. And in essence, what is Bitcoin? Just an exchange coin, which is no longer needed? And if all the tops cease to believe in the bitcoin and decide that not to be his leader and sell. Then Ether will replace the cue bitcoin.
