Many new investors may be confused about emergency funds but the simple solution is for only you as an investor to find out. For example the amount of Bitcoin you are accumulation every week/month through discretionary income is easily done. This simple consideration and what kind of safety wall should be built to continue the long drive should be decided by you. I mean if you have set a point for Bitcoin that you will continue to accumulate for maybe one or two or three cycles then you will be responsible for managing it yourself because you will have to consider how much emergency fund/floating cash you will keep with you as a responsible investor. The target will be to make Bitcoin accumulation long term and you are ready to meet any emergency needs in the period.
