It is true that the DCA technique can be used by anyone because both poor and rich people can use this technique, and even those with small incomes can still use the DCA technique and buy according to their means. However, even those without a steady income can still use it because the most important factor is desire. If one lacks the desire to invest in BTC, they won't be able to do so, as there are many wealthy people who also choose not to invest in BTC and therefore do not own any.
But the most important thing is that we must strive and work hard because there are also many poor people who eventually become rich by investing in BTC. However, one of the keys to success in investing in BTC is that we must be strong against temptation because there are many people who are not strong enough to resist the temptation of BTC, one of which is not being able to hold BTC for the long term.
DCA is really a method that can be used by both rich and poor because the main thing here is not a big amount at once, but consistency. However, anyone can do DCA when you are doing it with discretionary funds. If someone does DCA without keeping money for necessary expenses ad emergency fund , then if the market drops a little, he will be forced to sell when an emergency arises. This is the most common way to failure. So DCA is for everyone, if it is not money for necessary expenses but on top of excess money.
You said that DCA can be done even if there is no steady income, but its depends on desire. In investing bitcoin its not only depends on wish but also cashflow (although it may be irregular), planning, and determining the amount according to the condition are needed. DCA is also possible for someone with irregular income. But He has to allocate systematically after the income comes. For example: when the income comes, he will first meet the necessary expenses, then buy the fixed part of bitcoin, and create the emergency fund if it is not full for 3 to 6 month expenses . So even if there is no steady income, investment is possible if there is a proper plan.
You are right that many rich people do not buy bitcoin. Personally, I think that buying bitcoin is not a moral obligation. Whether a person will buy bitcoin or not depends on his willingness, preparation and ability. If you read JJG's
individual factors concept on this matter, you can get the right idea. Even if someone is rich, if his spending habits, lifestyle, or mental tolerance cannot take the volatility of bitcoin, he will not buy it, it is normal. And even if someone has a low income, if his discretionary is small, he can accumulate. But many poor people become rich by investing in bitcoin, it is very risky. Because it creates the idea for newbies that buying bitcoin is enough to make rich. The reality is that some people have made a lot of profit from BTC, but many people have made mistakes and bought Bitcoin with loans, leveraged it, panic sold, or went to shitcoins and suffered losses. Bitcoin may create opportunities, but it is not a guarantee that someone will become rich from poor. Your results depend on how you behave, how regular you are, and whether you can avoid forced selling for long time investing and holding mindset.
