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.
That is a very good thought, but you also have to realize that not everyone can think like that, especially those who don't like Bitcoin. Even though many media have explained that Bitcoin is very good and suitable for long-term investment using savings that are not intended for emergency funds in life. Because if there are many people who want to think like that by putting more money into Bitcoin investments without thinking about selling in the near future, maybe the price of Bitcoin will experience price increases more often than corrected.
