Do not invest all that we have in bitcoin, because there are still other crypto investment alternatives to be able to do, so we do not expect only one type of investment. In addition we must be able to control our emotions in investing so that we can invest patiently and calmly. Investing not only buy and hold, but also must understand the type of investment that we do and know the factors causing the movement of prices, so we will always get the results of the investment we do.
