I agree with you, an emergency fund is very important, because it is something that must be paid attention to, there will be a situation where we will experience something sudden and of course it requires funds to overcome it, such as an accident or other things, so we have an emergency fund it will help us to overcome something that can happen suddenly. Of course, even though we have parents, it doesn't mean that the needs we need can be provided or fulfilled by our parents, at least we also have to have good thoughts, by not burdening our parents to fulfill our wishes.
If you have a fairly serious problem that must be resolved with finances that may be quite large, that doesn't mean you have to sell your bitcoin investment. because in my opinion, selling Bitcoin investments certainly cannot be done haphazardly, it must be done and carefully. If someone already has a business then in my opinion it is mandatory for them to think about an emergency fund and have one.
Therefore, before starting investment, prepare an emergency fund in advance for at least 3-6 months so that the reserve fund is safe when needed at any time, of course this will not interfere with your investment when in any emergency.
I always use this strategy because for us it is important about emergency funds, we are humans who will certainly require expenses and needs that we never expected in any case.
Never rely on parents means you don't have independence, if you are still in school then it is still the responsibility of the parents but if you have worked you yourself must be able to how to support yourself and start the investment because with the monthly salary you receive, for example, it is important to set aside on investment, especially bitcoin if you understand it.
Now when you have a problem in the sense that there must be greater expenses then the reserve fund can be relied on, your investment is safe will not be sold in the middle of the road, you can still continue investing in bitcoin when things are normal.
But when your finances are still healthy then continue your DCA to invest in bitcoin.
