It is almost maximum certain that there is no possibility of losing money in Bitcoin investment, yet these messages are spread to prepare investors in advance. In my opinion long-term investment is not a gambling game that has the possibility of losing money. Or it should not be a trading endeavor that has the possibility of losing money.
In example is that you invest the amount you can afford to lose. This literally means that you should plan your investments in such a way that your floating cash balance remains intact and your real assets do not decrease. Another meaning is that you should always be prepared for the volatile price of Bitcoin to have financial security to keep you safe from any price level.
The ability to lose money does not mean that you will lose all your money. Another meaning I consider is that there is a level of risk in investing and that smart investors should plan for losses so that they do not have to regret it if the price drops too much. The positive side of having a negative mindset is that you are mentally prepared for a bad economy and if the market situation improves in the meantime, it will increase your level of financial stability.
I've spoke about something similar but then I think I'll still give my opinion concerning this particular discussion so some folks would understand better, cause I see some misunderstanding somewhere, or should I say misplaced phrases, when it comes to Bitcoin investment, saying that people should invest what they can afford to lose is misleading, cause it's not something that profits is gotten by luck or chance it's something that involves the future, a long-term process and not relating with gambling or trading that involves luck, speculations or predictions to make profit, you buy the coin, hold it for a longer period and hope to get better profits in the future that's why instead of using the term, (investing what you can afford to lose) it's better to say that people should invest according to their income or financial capacity, the other one is confusing and relates with gambling or trading. Doing the DCA alone already mean that an investor is prepared for the volatility of Bitcoin, it doesn't affect the DCA in any way so let's be guided concerning that. Some folks are yet to hodl Bitcoin for a longer period yet they're considering the risk involved in it, how can they tell when they've not got better experience, however experienced investors that's invested for a long period can testify that investing in Bitcoin comes with less risk and one is bound to profit so far they do it the right way which is buying and hodling for a longer period at different Intervals and according to one's financial capacity, not investing in what you can afford to lose.
