Make me understand something here, are you saying to save up for 3-4 months before starting to invest?? Or are you saying to only save up to 3-4 months worth of emergency funds at a time??
If it's the former, I will have to disagree because spending 3-4 months on just saving while you could have also been investing will have delayed your investment by that 3-4 months And that will have been a loss on your side as you could have already been accumulating bitcoin. If it's the later then I don't fully support it, your emergency saving should not be limited to just 3-4 months worth, this might seem like alot but I will ultimately not be enough depending on the kind of emergency situation that comes up, I believe a person should always keep saving.
Earlier investors used to save money like this for three to four months or more before investing and then invest with that saved money, but now the style of investment has changed. Now investors don't need to save money, but now the amount of money that investors used to save every month, every week or every day, they directly invest in Bitcoin,DCA investment strategy. If the investor buys bitcoins step by step without saving money, then it will be seen that when the price is there, the investor will buy bitcoins, so that even if the market goes up and down, the investor's investment will not have a bad effect. This investment strategy is generally considered as a smart investment strategy.
So those who are interested in investing can start their investment at any time without saving money.
You have mentioned here that the previous investors have mentioned the method of saving money for three months or four months, they may have saved money to form an emergency fund. Because I think everyone is at risk of life so it is important to save people three months or four months or even more money to deal with the risk. On the basis of your bold part, I want to say that investors still need to combine money but if not investing only money, it may not increase according to their needs. Because we know that Fiat can never give people profit but Bitcoin investment will help investors to earn profit at any one time on a long journey.
