There is no way that I see any of the altcoins overtaking bitcoin even the ones with really good project. Bitcoin being the first cryptocurrency in the market already gives the coin bragging rights and to maintain relevance through all of the years in the midst of thousands of coins has helped it to solidify its place as the best coin in the market and no one can replace it.
Yes absolutely , currently there's no Altcoin that could be considered competitive to Bitcoin .
Bitcoin is now almost accounts for more than half of the total crypto currencies in the world ,
In the observable future I can't bet on any Altcoin to come even near as Bitcoin.
