From a speculative point of view, yes.
From a real usage point of view, it's a bit more questionable. I still spend BTC where I can, which is more often than some people seem to think.
the speculations come from the people and they are the saying of the people who have spend time in bitcoin and experienced many events in bitcoin and have studied bitcoin. Based on that things they can predict the future of bitcoin and as every user of bitcoin is of the view that bitcoin have a future then it is right.
