i think those people who are getting benefit from bitcoin must be thinking and caring about the future of bitcoin. but in fact most of the people do not think so. for example i am getting a good profit from bitcoin trading and alt coin trading so must be thinking and wishing the future of bitcoin more birght and successful.
By actively participating in stream of bitcoin funds alone is enough for us to keep bitcoin still exist for the future, no matter we want to buy or sell in high par. Btc is a "life" for me, because with additional income makes me moved to prioritize as an economic goal.
