If an amount like $20-$30-$40 can be invested continuously in the DCA method, then it can become a very large asset over time, in fact, the amount of investment does not matter here, here the most important thing is to deposit Bitcoin continuously with long-term faith, you can keep buying Bitcoin continuously with any amount of money according to your ability, but it can become much bigger than your expectations over time, because the chances of success of Bitcoin are very high and the future of Bitcoin is bright.
I agree with you that the amount is not important, but holding it in the long term is the most important thing. The real proof of this is that those who spent only $10 on Bitcoin at the beginning of Bitcoin and held it until now are at what level today? They have certainly become the owners of a lot of money today, although the number of such people is very small.
Maybe history is not possible to repeat itself in the future. We may not be able to profit so much in the future, but if you trust Bitcoin and hold it for the long term, you may not lose, but you may profit more than you expect. Without delay, even if you have a little discretionary money, try to be consistent in planning for the long term. However, a very small amount may not be investable.
The most important thing is to stay consistent in maintaining your Bitcoin investment, you don't have to have a stable source of income to invest in bitcoin, as long as your discretionary income is available continue to accumulate, no matter what the current price is, because you are an investor, your main goal is to buy to hold it long term,
Today those who delay investing in Bitcoin will regret it in the future, because in 5 to 20 years time you will see the highest price you have never seen before, much higher than the current price and the current price of $112k that you think is too expensive will feel cheap in the future, so just focus on continuing to accumulate, not now but you will feel the benefits in the future.
You said that a very small amount of money may not be worth investing. The part of the discretionary income that will not affect real life if lost is the part that is invested. Everyone's financial situation is not the same. However, it would be better if someone continued to invest $10 from his discretionary income regularly than sitting still. Yes, the amount may be very small. But it is possible to profit from this small amount of money. When someone continues to invest even if it is small, it will develop a regular investment mentality in him. If he invests a small amount in the DCA method, his investment will have less risk. And he can at least be a partner during big growth. So in my opinion, it is more fruitful to start consciously even if it is small.
To start investing even a small amount of money can be a great start if managed well and consistently, with today's technological advancements, many platforms allow us to invest with very small amounts. So more people can be motivated to start building a better financial future, without having to wait for a large amount first. On the other hand, this can certainly shape the mentality of investors, which is an important factor because it is habits and mindset that determine financial success, not just short-term decisions.
