Do you really feel you can make investment with the intention of losing the money? If you have the conviction that you will lose the money, it should not be called investment but gambling. I have come to realise that the phrase "what you can afford to lose" may not be right for investment especially an asset like Bitcoin that we do not have record of anyone, who treat it as investment, losing money. So I think the right way to put it is to invest what one does not have urgent need of such that the investment can be held for long without affecting the investors living condition and basic needs. I got wind of this new twist after observing several deliberations in this thread and others and I have come to the conclusion that many people urging people to only invest what they can afford to lose, does not even have any money they are willing to lose.

Those who have the mindset of holding Bitcoin are never afraid of loses because Bitcoin has this unique way of bouncing back even after prolonged down trend. So far, Bitcoin have consistently proved them right that loses in Bitcoin is more pronounced for short term holders.
