The idea of investing no more than you can afford to lose is the same as making sure that you are investing within your discretionary income and not using money that you need for expenses. Also bitcoin is not guaranteed to be successful, so everyone should realize that he could lose up to 100% of what he puts into bitcoin. Surely no one invests into bitcoin (or anything else) or even engages in trading with any intention to lose, yet they still need to account for the possibility that they are not using money that they need for their expenses whether expenses in the coming month or two or even expenses down the road.
That’s true eventually as, the idea of how Bitcoin investments should be approached and I agree on the not having a 100% guarantee on it but, it has some guarantee none the less, especially when compared with the many altcoins out there. Bitcoin has more proven guarantee then the lots of them, deeply rooted in its price history and how it’s carried despite many critic and attacks.
Most people don’t see bitcoin like that and they have an 100% guarantee that bitcoin will be successful after their investment in it. It is good to have such conviction because without that, you won’t be willing to put some money into it. The saying that goes “invest what you can afford to lose” will actually come to play in this case. If you’re doing an investment without any sign of been profitable, you won’t have come into it the first place. The nature of bitcoin makes it unpredictable to be successful or not but all investors in it are optimistic of it. No one wants to lose their investment in bitcoin, infact everyone is 100% sure that their investment will yield profit in the end, but we should not forget that bitcoin is an unpredictable and volatile assets, it may or may not go well.
So, invest what you can afford to lose even though it has been proven since inception to be on an upward trajectory price till date. Investing what you can afford to lose will also not bring the thought of having to touch your investment when you need some money, you would have made up your mind by then for the money to be what you won’t touch for any emergency funds, that would have already been set aside before starting the investment in bitcoin.
