You do not have to establish your emergency fund prior to investing into bitcoin.... especially since with bitcoin, is it important to get started investing into bitcoin as soon as you figure out that you are interested in investing into it and that you have discretionary income that can be used to invest into it and that you are expecting not to tap into your bitcoin investment for 4-10 years or more.. which surely can feel like a long time for people, but that should be a bitcoin investment mindset in regards to figuring out how to treat bitcoin as an investment rather than as a trade.
We often get confused about emergency funds and some may think that the need for an emergency fund should be set from the very beginning. Having a clear idea of the fund can make small investors more courageous. It makes investors more mentally prepared to manage a 4-10 year DCA/accumulation regularly for a longer period of time. It is recommended for interested investors to have an emergency fund to accumulation more Bitcoin so that over time they feel more secure and feel better about holding Bitcoin for a longer period of time.
A smart way to accumulate Bitcoin for a prudent investor is to run DCA strategy by running his/her continuous stashing. Many new investors find it very challenging to start with Bitcoin and if they are constrained by their emergency fund, they may find it even more challenging. So for easy Bitcoin accumulation, one should start by deposit any amount every week/month from prudent income. In the coming months/years those investors will continue to feel the need to increase the amount of floating cash at their convenience to secure their Bitcoin stash
