I dont think bitcoin will kill off all other ALT coins. Imagine 5 or 10 years from now end users are selling their products online and accept multiple forms of payment BTC, ETH, LTE, etc. Why not???
I think BITCOIN will be a STRONG crypto. It will be the mother of all cryptos, people will buy it to branch into other ALTs if need be.
i did a little rearrangement here and this much is right (except the strike-through part), there is no argument that in the future bitcoin won't be the only cryptocurrency that is being used. it is pretty much possible that new altcoins can become big and strong.
but those altcoin are not the ones you might think and especially ethereum which will never be in that list because it is just a pump and dump coin with a lot of manipulation behind it to keep it alive.
Just look at this chart here.
http://coinmarketcap.com/charts/#btc-percentageThis is the total percentage of the market that Bitcoin dominates. And since the beginning you can see that the peaks are becoming less and less. So this means ALTs are taking up a bigger percentage of the total Crypto market cap.
the only thing that this link proves is that bitcoin price is now somewhat stable, so the trade volume of bitcoin is lower and traders are looking elsewhere to earn some profit and what is better than pump and dump coins.
in other words the highest volume altcoin is the most pump and dumped coin of this year.
