as far as i understand bitcoin became more popular and it have many users around the world, if we want bitcoin to be adopted by everyone in this world, bitcoin will need to take upgrade and innovations. It will happen time to time as this will be the pre-requisite of our world and every things, if it not be change so upgrade it. In ths manner bitcoin will survive. as every developer still searching for its solution very hard WE bitcoiner have different side about it we dont have a centralize system so there no good or bad about it.
There must be some amendments and improvements in bitcoins to keep interest of people. It has already been working on the transaction fee and speed but if we give a second thought, what improvements other than mentioned can be made.
Bitcoins is already giving everything. Can you tell what kind of change you want to see in BTCs ?
