Your emergency funds should be set up in order to take care of any unforeseen circumstances that will arise during your bitcoin accumulation journey. If you don't set up emergency funds as you have started your bitcoin investment, you are only gambling because DCA wouldn't save you from unforeseen emergency when it arises. No matter how little your discretionary income is as you have started your bitcoin investment, you need to set up your emergency funds of at least three months of your income as a backup to your bitcoin investment so that you don't sell your bitcoin investment when it is not of your will.
Some people that are saying emergency funds is not really needed, some of them are not even investing in bitcoin, because if you are really investing in bitcoin, then you will know how important emergency funds is. I no longer argue with people unnecessarily, because some people you are arguing with are not even holding any bitcoin, and some might not even have any plans to invest in bitcoin.
If you are not having a emergency funds, incase if anything arises, then you won’t be able to take care of it, you won’t have choice than to sell the coin which you bought, but if their is an emergency funds, then you won’t even think of selling the coin which you bought. We all know how volatile bitcoin is, and when you are planning to sell when emergency arises, then you might even be at lose at that period of time, so emergency funds is important, and don’t even think you will be investing with it.
