though am new to the whole Bitcoin world and it's concept but in addition to what mr suevie said, I believe having some qualities without a strict policy to fall back to will result to an incompetent investor as trying times may arise which could cause panic, policies are actually the building foundation of competency and when you don't have one trust me the outcome would be a disaster.
If an investor really acquires all the needed information or education about any investment (in Bitcoin) they are making, then they will be ready and prepared for any "trying time (emergencies)" like you mentioned. The bitcoin price is always volatile, and it's not an asset that you can just assume will take profit within one or two months; you really have to hold it for a long time before you can make much profit. Another thing is that when you are aware of how volatile the market can be, even if the price of Bitcoin dips below the price you bought, you won't be in a panic and will not sell off to incur a loss.
