You are right. When we encourage others to invest in Bitcoin, we advise them to be able to afford to lose the amount they invest and it is a fact that the chances of losing money are very low or close to zero. Depositing Bitcoin with their hard-earned money and where that money is coming from should be the right method and investment style for each investor. To avoid the mentality that when you accumulate some Bitcoin and have to fight the market crash, investors are told to invest the amount they can afford to lose. There may be some other reminders, including that they should not feel the need to sell quickly and should continue to save continuously. I think it's a struggle to invest, you should simply consider that you are on the right way and that it will get you to the point you expect.
You are right that investment is a struggle. In that struggle we have to fight strongly where there is no point in having any weakness. If in this struggle the money you use is a place of weakness then it is very difficult for you to win the struggle. Because that weakness will force you to back down again and again and you will lose the struggle, along with the money. If you can give up the illusion of money in that struggle and fight for success with strength then you will also win the struggle and you can achieve the greatest achievement in life from that struggle.
