Emergency funds sometimes can be very important as it help one to relieve financial pressure or any other challenge and according to your instance, that if someone is being paid $100 and then he/she uses $50 as emergency funds and also uses $30 for accumulating Bitcoin maybe a DCA method. that's a very good one but in my place I think $100 won't be even enough to buy what you will eat because of the economy talk more of to use 30% of the money to invest in Bitcoin what it means is that if you try it you will be so frustrated and confused on what to do in fact your investment in Bitcoin will be disturbed. Before someone should or will invest in Bitcoin he/she should make sure that they have enough money that will make them stay off from their investment.
By having an emergency fund, of course this will really help us to be able to achieve the profits we set in the investments we run. Having a mediocre income will of course be very difficult to be able to run investments well because before someone can meet the necessary needs I They feel that it is not natural for them to invest and if they force themselves, of course they will have difficulty if they are in the process of investing and they need the funds, then they can take the assets they have and if they are in a profitable situation, of course this is not a problem, but when they need these funds, the assets they own are experiencing a decline, of course they are at a loss.
Yes, of course it would be better for them to invest first and be able to prepare funds for emergency needs that they need to be able to carry out investments without being disturbed by the need for emergency funds.
