emergency funds is very important that every bitcoin investor most have but it not that necessary that someone most have emergency funds before it can start it bitcoin investment
IMHO.
It's important that someone has an emergency fund before they invest in any investment or to Bitcoin.
Why? Because if someone spends his emergency fund into investment and they need it for what it is intended for.
You'll get the picture of what will happen next and that's about selling that. So, it will become no use if someone wants to invest for the longer and yet they have to sell it for some unforeseen event.
Having emergency funds is a good idea, but I don't think it's necessary to have it before investing. I think we can plan for that while investing. Having multiple sources of income is something I think is crucial for new investors because it will help them reach their financial goals and allow them to save for emergencies from their income.
Emergency fund is needed only after starting investment, that is why emergency fund is needed where you can continue investing Bitcoin regularly on a weekly basis. Investing Bitcoin according to the DCA method will allow you to buy Bitcoin regularly and you will also be able to hold it for a long time.
If you spend time in illness, then you may refrain from investing because you may not have money saved, then you can invest Bitcoin from emergency fund. Regular DCA method will be followed to deal with danger and to sustain Bitcoin investment for a long time.
