It has a chance that one altcoin will go battle against bitcoins in cryptocurrency markets.Current big altcoins like eth ltc and dash has the chance now to go up against bitcoins if just this altcoins will have more support like bitcoin has at this state.
Well i dont see that altcoins has a chance to beat bitcoin, even that it has a lot of altcoins in the market i dont think it has a chances against bitcoin, Bitcoin price is to high and the popularity of bitcoin is also high compare to altcoins and bitcoin is the strongest cryptocurrency so altcoins has no chances.
Now there is probably no chance but the story of the future, no one can predict, although bitcoin is having an overwhelming reputation and possessing a strong support community but it is not perfect, it still has problems and does not please the fans. And because of that, altcoin will still have a chance in the future when altcoin exploits and improves the issues that bitcoin is facing, some evidence that altcoin is generated based on bitcoin is very much, it outperforms bitcoin in some issues as the cost is low and the time to complete the transaction is very fast
