We don't invest into something and yield bad outcome in our thinking, a good investor will always even at his lowest remain positive to his investment, this is where it sits the difference between gambling and investments. We gamble with what we can be able to lose because our chances of getting profits from it is limited, so we deploy such methods in order to be on the safe side. Whereas In some scenario like more of a physical investment one can invest with a lot more than he can afford to lose because it's a very rare possibility of the investment collapsing. For example, building a house for rentage which we know the drag associated for owning one, what will be probability of finishing the building and not having no one to rent out the house. But in a good sense, and some specific investment deserves a compilation of both to be successful.
You are basically getting what the post you quoted wrong and I perfectly agree with the member. There is no that investment that doesn’t comes with risk, the only difference is the risk is just more in very volatile assets than in solid assets but still the risk too is there. Investing what you can afford to lose also helps you to be able to hold on to assets very well and not panic due to having extra funds to fall back to if anything goes wrong.
Yes we all know bitcoin at the moment cannot come down to zero in value but still it can dip and probably the dip might be for a very long term which would create panic to the holder most especially if he uses funds that he can’t afford to lose and needs them Back. Even solid and physical assets also Carries its own risk. The housing example you brought is also a risk because the house can get damaged by any of the means like fire hazard or so and with this if you have invested what you cannot afford to lose then falling back will be a very hard thing to do
