I guarantee that it will never be possible because bitcoin is the coin that is the main part of all cryptocurrency, the price of ethereum and ripple also has price movements depending on the movement of bitcoin.
And in fact until now when the price of bitcoin is down, there is no altkoin that persists and can outperform the bitcoin which altkoin follows the movement of the price of bitcoin and now the eth position has been shifted by xrp which is previously second to now eth is in the order three.
not ethereum or ripple, or no other coin.
bitcoin will be always first coin of market forever. other will be stay as "altcoin" always.
