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.
