Yes, the DCA strategy is one of the best strategies for beginners and users who have small capital, when they want to trade Bitcoin and also invest.
When you set a strategy for buying Bitcoin and calculate the budget that you have 20 percent to buy Bitcoin every month, of course this strategy is a long-term strategy and is to increase Bitcoin income in the long term.
I think there are many ways to trade and invest in Bitcoin, but the DCA strategy, in my opinion is the best strategy for those with small capital, as opposed to large investors, such as companies and so on.
It's useless to DCA on trading because you will lose it all at the long run and I don't see it as a smart move. DCA is used for wealth building overtime because you will gradually buy everything that your discretionary income is available. Bitcoin is a long term investment and deserves to use DCA strategy to accumulate it overtime but trading is like gambling and whatever, amount of money you put into it disappears into the market.
It's wrong to advise a beginner to trade and invest at the same time because he has very little or no knowledge on the best way to go. New investors should focus only on bitcoin long term investment and how to keep their bitcoin accumulation ongoing with DCA till they reach their bitcoin target.
Trading can never be investment, and investment can never be trading, the two are different in two ways. You will not get any short-term results from investment, whereas after learning trading, people trade for short-term gains. But the main thing is that you will not get success very quickly from either, because investment is usually long-term, and on the other hand trading is a very deep subject, and so if you want to learn trading well, you will have to learn trading by spending a long time. And a new person must be informed about this subject in advance. Whatever you start, trading or investment, you will not be successful from either, rather after starting, you will have to spend a long time in whatever you do, and only then can you be successful. So the main thing is that you have to abandon the idea of getting rich overnight, and move forward with a realistic mindset, and after all, nothing is risk-free, and so it is also very important to consider your own capabilities.
