mh... no. Bitcoin have brothers, but it will not be replaced. just my thought
I would recommend you to write longer comments if you really wish to join some good campaign.
But I am agree that bitcoin will be replaced by some other crypto currency. Bitcoin is the most known and the most stronger from any crypto. The possible future of bitcoin that I can predict is that bitcoin will swallow some other crypto and it will be only the one crypto currency with some one name.
