If one can save bigger amount for emergencies in 9 months, he should just concentrate on the investment for some times until the emergency funds is low then he can continue saving for emergencies, like after removing the monthly expenses from the monthly salaries hes receiving then he should just put the rest of them into Bitcoin.
You seem to be struggling with the idea of an emergency fund.
Lolz, he thought emergency fund is something one can save and be using it in the future. Well government might do that because they have enough funds to be used in the future but I don't think so for individual I don't think so but in the cryptocurrency investment, emergency funds is the cash you have aside from the main investment funds and that will also the clause I have been using that, "have something doing before you start your investment, you that you won't spend your investment funds, and what you are doing can be your emergency funds. But @JayJuanGee can explain more better for everyone's understanding because the "Emergency Funds" here is like giving extra meaning to the conventional meaning. And that might be the misunderstanding of some us because they might only understand it from the dictionary and general uses of the "Phrase".
And as it said earlier, emergency funds are not easy to save or keep because problem arise in human life every day so if you are keeping more to invest then you have to displayed yourself for some minor occurrence but even that is to not easy to bypass. But some people used to keep or luck emergency funds in apps to be use in the future, so when Bitcoin price low and you have emergency funds at that time then it is good for you to top up your wallet with good amount of Bitcoin if only you have enough emergency funds at that time.
