I think not for now,as a widely known currency people keep talking about bitcoin and not etherium or any other currencies.Although eth,litecoin etc. has already have their own value in the market but then again their prices has backed up with bitcoins price.The father of all crypto can stand alone not depending on alts price that is why i can see that the achievement of bitcoin has been too far from the achievement of  the existing altcoins for now.Bitcoin has gained the trust from its user and holder and to be obsolete is not the basis because until now bitcoin is still the trend that everyone get hooked.
