When it comes to bitcoin investment there are things that are important to have and one of them are reserved funds, like you said it helps one when there's a dip, when you are using the DCA strategy and you have also built a very good reserved funds it will help you accumulate more Bitcoin than someone who is just using the DCA strategy without any built reserve funds.
Dollar Cost Averaging method invests as much as you can afford i.e. you can start with a small amount even if you don't have a huge amount of cash. Investing does not mean investing all the money you have. One thing is true that we need a certain source of income or funds before investing. Whenever you have a fixed source of income, you can easily meet your needs with the money you earn from it and continue your investments comfortably with the reserve money.
Moreover, reserved funds play an important role in investment. Because if you have enough funds for investment then no matter what happens in the market you will be able to keep your investment active by buying bitcoins regularly.
I know reserved funds are very important in Bitcoin investment, but as a beginner who just wants to start investing in Bitcoin, I don't think that he or she has to have reserved funds before they can start accumulating Bitcoin. If they start looking for reserve funds first, when will they actually begin investing? That can even discourage them. I think the best way is for them to start investing in Bitcoin first before thinking of reserve funds. What is necessary is to always invest what you can afford to lose, and by using the DCA (Dollar-Cost Averaging) method.I believe that with this method, they may already have some funds set aside because the DCA method helps ensure that someone is less likely to remain completely without funds. In case of any emergency, they can easily handle it. I think that as long as someone is investing what they can afford to lose, it will be unlikely that an emergency will force them to touch their Bitcoin investment. This is because they will only be investing a small portion of their salary, which means they will still have enough in their bank account.
