But saying that we should invest with an amount you can afford to lose makes it looks as if we are gambling or we are trading, this is an investment, no Investor will be happy losing his hard earned money, so in my own opinion, the right statement for such phrase is invest with an amount you can do away with for a very long period of time.
You are making the statement very complicated. Losing money does not mean that you are going to lose the money or that you will easily lose it. You can take this word to mean money that you will never need to meet your daily needs or meet basic needs. Or even if that money is ever lost, it will not affect your quality of life or you will not be paralyzed. I will not say that after investing with losing money, you will not regret it if it is somehow lost, this sentence is not realistic at all. A person's hard-earned money is always valuable and if its amount is very large, then you will definitely regret it if it is lost.
Choose money for investment that if it is lost one day, it will not have a negative impact on your quality of life. I find the definition of losing money as you have mentioned a bit confusing. According to your definition, if you need the invested money before achieving your goal, then what will you do or how will you mention it?
It's actually quite simple, why should someone invest in bitcoin using money they can afford to lose if something bad happens. This is because investment certainly has a high risk, as does bitcoin. Although it is true that bitcoin is a decentralized investment asset that cannot be manipulated by anyone, there will still be a risk. So that's why to overcome this situation when investing in bitcoin we must use cold money. Because if an unwanted situation occurs, such as a loss, of course it will not make you too stressed. Although it is true that even though we use cold money, disappointment will definitely still be there if we experience a loss. But the positive side is that it will not interfere with our other financial arrangements. Because it is true, no bitcoin investor wants to lose their money. But here we have to think realistically, because basically investment certainly has the potential to experience losses. So get used to this, and don't take this too seriously. Because if it is too excessive, I'm sure there will be a less than good impact that can occur on your mindset.
