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.
It is as a result of the problems of emergency needs that every investor is advised to make room for savings aside while carrying on with the DCA investment plan. An investor is more likely to make success in his investment having an existing savings plus a reliable income source as it is a dyke against challenges that could make investor tamper with his investment. A good investor should be able to delineate a systematically way of investing because it is out of a lack of knowledge that newbie investors do go all in while investing in bitcoin.
