Is bitcoin able to survive long term?
I don't know what the first paragraph has anything to do with this question you are asking here apart from making your post long but bitcoin is a new technology which has been growing constantly for as long as it has been alive. it is impossible to say whether it will survive or not at this point. all we can see is that bitcoin has the potential to grow much bigger and be improved a lot more at the same time. and so far it has been doing exactly these two so there is a good chance that it will in fact survive for a very long time, possibly during our lifetime until another new technology comes along in 100 years and replaces it.
