When it comes to bitcoin investment, we should not invest all of our money in it so that we will always be able to solve our financial needs when they arise.
This discussion has been treated more than ones here, so I believe every investors or a beginner should be able to understand the concept that keeps their investment healthy and running however I believe this is one of the reasons why at @JayJuanGee introduce the method and the reason why an investor should have an emergency funds and also a reserve funds was actually because of a situation like this so that with a proper utilization of it an investors could hardly run into a problem no matter how it may be, however just like you said is not an investment wise to put in everything you have on investment because with the lack emergency funds or reserve funds their is a big chance of getting into trouble on the process.
I think you need to follow some small rules for investing. If you rush to invest when you don't, you will face big losses. We need to know some good rules for investing and what are they. Apply and invest.
We should invest only as much as we will not face any problem and after investing we can live happily and peacefully with our family. There are some people who think of investing with money loan. If they face loss after investing, then I prepare to invest thoughtfully when I think about how they will repay the loan and how they will manage the family. If we want to do good all the time, we must have a good interest in investing.
