i strongly disagree with the above point as the bitcoin happens to be the father of all coins and has proven itself over time that it is in control of the technology and thus cannot be over thrown. that ethereum has come and taken some great changes in the technology by creating a smart contract opportunity does not in any way keep it ahead of the bitcoin.
I partly agree with your idea. But on my own opinion, they both are the future of crypto currency world. They both never fails to prove themselves that anyone can rely on them and they can rise a great value for long period of time. With there well-organized and well-established management, there is no doubt that they can do what we dreamt for them. We dont need to fight whose better, but we must be optimistic and think carefully that we both need them, not just them but for all the cryptos. Support any coin and for sure you'll receive something good soon and we will have a better future.
