You should believed in bitcoin if you have investment and i think you are here because you believed that you can earn lot of money in terms of bitcoin because people who does not know about bitcoin is not a believer.
yeah because it believes in bitcoin might help you to make a profit in bitcoin, because believe it or not there will be a lot of speculation that advocates against bitcoin, maybe believe will save you against panic
Only believing in bitcoins will never give you profits but you also need to work on it to make more money from it in future and the higher price of bitcoin in future will only depend on the adoption level, if people will not show any interest in using or investing in then bitcoin may disappear in future.
