I think every person should have an emergency fund before planning an investment because it is not the case that he needs an emergency fund at the time of investment.An emergency situation can arise at any time from birth to death and an emergency fund is needed at any time to use this time, so I think that when a person starts investing in Bitcoin using his discretionary income, he will already have an emergency fund. What needs to be done in this case is to add money to the emergency fund. And invest in Bitcoin from discretionary income.
When there is an emergency fund along with the investment fund, the investment fund is very safe. When a person is in an emergency situation, he needs money and if this money is available from the emergency fund, he does not need to touch any other fund. That is, the emergency fund protects the Bitcoin fund. However, when an amount equivalent to meeting the basic needs of at least three months is deposited in a person's emergency fund, then someone can reduce the supply of money in the emergency fund and increase the DCA of Bitcoin if they want. That is, then there is an opportunity to buy a little more aggressively than before.
I think, you should have read the replies on this thread before saying this because I believe that it has been repeatedly said here that you don't need to waste more time building an emergency funds before getting started when you can build both your bitcoin investment and your emergency funds at the same time in order to kick start your bitcoin investment immediately, you discretionary income is available. Instead, of piling up fiat for an emergency that may happen or not.
If any brand new investor doesn't have any money on ground as his backup funds, there's no point trying to have one on ground first because putting your money into a valuable asset like bitcoin is very important since, fiat depreciates in value overtime. It can take a low coiner up to a year or more to build his emergency funds up to three months of his monthly expenses which is a very long time and you want to sit down like that without buying any SATs, it's not a good way to start with.
I have always told people that anything that involves waiting when it comes to bitcoin investment is a bad strategy to increase your bitcoin stash because you will lose a lot of opportunities in the market. The more you're waiting, the more bitcoin price is increasing and you're getting old at the same time giving you a lesser opportunity to have a good size of bitcoin in the future. You can share your discretionary income into three equal parts and use one part for your weekly DCA and the second part for building your emergency funds because it's important to strike a balance between your emergency funds and bitcoin investment in the beginning. The last part goes to your discretionary consumption.
