Example let's say I want to start investing right now in bitcoin and I have a monthly income of 1000$(it's assumption figures) and I decide that I want to invest about 300$ from that amount into a weekly DCA investment which should be about 75$ weekly invested in bitcoin and then I also had some cash from my savings that I also wanted to use to invest in bitcoin maybe to give myself some kind of head start and the money was about 3000$ and I decide to use 1500$ to invest right away, that is what a lump sum buying would mean.
Assuming your monthly salary is $1000, now you will invest $1000 every month or every week consistently. In this case, first of all, you need to confirm how much money you can spend every month on family management, children's education expenses, electricity bills and other sectors. Once you figure out these expenses, you can of course calculate how much money you have left over at the end of the month. You can consistently invest 60 to 70 percent of the money you have left over, minus all incidental expenses, within $1,000. After investing 60% to 70% consistently, you can save the remaining 40% or a part of 30% and keep some money for your spending. If you can invest with this plan then I am sure it will be very easy to hold your investment and you will be able to keep your investment for a long time and you will be able to consistently maintain your investment consistency.
It's OK to invest in the DCA method. Assuming $1000 or more, you can easily work out the numbers on paper no matter how you calculate them. It is easy to say but very difficult to do. But I'm not belittling you here, you definitely can if you try. However, if you get a $1000 salary, the most important thing is how much money you can save there. As people's income increases, their needs and family luxuries increase, the more you can control yourself. How much are you able to face the challenge of saving money in particular terms? If you can control the amount of your monthly salary, your spending rate from the first week of the month to the third week of the month, you can execute DCA properly by applying the investment in the last week of the month.
