Emergency funds should be used for a real life emergency and that should be set up, immediately you have started your bitcoin investment, if you do not have anyone available before you decide to start investing into bitcoin. You don't need to put them in place before you start your bitcoin investment because it will waste your time from getting started early and start building your bitcoin portfolio.
You can share your discretionary income into two part and use one part to DCA weekly overtime and use the other part to build your emergency funds of at least three months of your income. When that's done, you can channel the money for building your emergency funds into building a reserve funds. It can take up to one year or more to build these backup funds and that's the reason why if you don't have it available already, you don't need to be waiting to build them before starting your bitcoin investment.
