In my own case, if bitcoin went on a bullrun today, i will first divide the entire fund into two category, first one will go back on investment while the second one will be use to make investment on other days physical assets in other for me not to put all eggs on the same basket, this is the best way i see the use of an investment for ones posterity, i will invest and keep being an investors because there will always be a sure means that we can always rely on that the price of bitcoin will last and also increases in values with time.
