I agree with you, now that new coin coins appear with a rapid development, and of course with a varied price that allows coin coins can evolve in accordance with the project and the price.
I dont really think that the other coins move faster over bitcoin and i still believe that the development of bitcoin is still more fatser than the rest of all altcoins and there is no doubt that before this year will end the prices of bitcoin will really increased very high.
The truth is, you are wrong. The other coins move faster than bitcoin and they are keep on developing the other coins compare to bitcoin because bitcoin is already stable in terms of features and it doesn't need that much of modification to stay in shape but the other coins are keep on adding more features to their self because they keep on improving so they can beat bitcoin.
