Friend, it seems like you don't understand what I mean, because the important point I want to convey is which is safer to do when investing in bitcoin. Because having an emergency fund before investing in bitcoin is not wrong in my opinion. Because you need to know someone who does not have an emergency fund in his life,
Wether having an emergency fund before you even think of investment or starting it when you have began to invest there is no difference because they all matters, although some will say having before starting is the best and i will also agree to that because if you were able to have $3k as an emergency fund do to how long you have been adding some amount on it considering the irregular price nature of things it will definitely help you because as you have now started the investment you will no longer be thinking about sending money on the emergency side because you already have a large size of emergency so you will now have a full concentration on your Bitcoin till you see that your emergency is beginning to drop before you can start sending some funds on it again.
