I am glad with ethereum could replace of bitcoin some day later, many investor keep holding ethereum will be happy because seeing ethereum have higher price than bitcoin, but is not be true because price ethereum and bitcoin today so far and never could raised half or bitcoin price, although with eth situation today look down.
That is almost impossible when an altcoin can replace BTC. BTC has always maintained its position in the market, most of the market capitalization of BTC accounts over 70%. Altcoins are recovering slowly and that does not mean that it can replace BTC.
