Great post, and I have to say that I agree. At first I was a big fan of Bitcoin, but I also got more and more interested in Altcoins.
I like to compare it to aircraft. The first aircraft ever by the Wright brothers was absolutely awesome, but can hardly be compared to the aircraft we fly today. It takes tons of time and human effort to develop a technology to its full potential, and this is exactly why a lot of Altcoins will eventually overtake Bitcoin.
Bitcoin is just a brilliant idea, but will certainly be surpassed by Ethereum or Litecoin for example.
