I believe in the potential of bitcoin in the long run to give a sweet value based on real life adoption and usage, but assuming a strong correction like the OP said, or just assuming a huge price for the future, is just what has turned this market into a purely speculative market and that is not helping.
Yeah it is right and that is the reason that people are not investing in bitcoin. This attitude will continue for long time. People will wait for the good times and good times will come when people will invest in bitcoin. Both are waiting for each other. When the investment cap goes up the strong corrections will also diminish, but the problem is that people are waiting for corrections to stop.
