In any type of investment, especially in assets like Bitcoin, which are high-risk, it's crucial to equip yourself with the right knowledge. This way, you can make informed decisions and avoid being swayed by your emotions. While others may panic and sell, you can stay calm because you understand the market's dynamics.
As a beginner you can start if a small amount since you don't have much knowledge on bitcoin but only the basic which can help your start your bitcoin journey. And as time goes on while buying regular, you can decide to study your investment deeper to know all aspect of bitcoin. It shows that you will learn faster than whoever that is seeking majority of bitcoin knowledge and understanding first. This is because there are some strategy that you will learn when accumulating that will suit your income base on the fluctuations in bitcoin price.
Since you are not planning to sell in a short period of time, there is nothing to learn much about the market because, you are using DCA to increase your portfolio, no matter the price of bitcoin at that moment. I can still tell you that there is nobody that can learn everything about bitcoin because, because everyday the technology is been upgraded with new features and the old bitcoiners will also learn this new development.
This is why your should start investing early than waiting to have the majority knowledge of bitcoin before investing. I believe that this is the best way for a beginner to start his bitcoin journey because time waits for no one, the earlier that you start investing in bitcoin, the higher chances you have of increasing your bitcoin portfolio with time. It is better to be a lowcoiner with the basic knowledge of bitcoin than a nocoiner with all the knowledge of bitcoin.
