I am also a person who has a monthly salary and works in the government, For investment I focus more first on my family's monthly expenses and for investment I allocate buy BTC with DCA according to propriety, sometimes this month it can get 0.00047 BTC and sometimes next month it can be up to 0.00067 BTC.
Since you are using a good strategy to buy bitcoins, I think it will be beneficial for you to buy. But you must keep in mind that investing should never be short-term thinking but for the long-term you should invest and hold the fraction of bitcoins you will have. Since you are a working person, and you are running the household expenses from your monthly salary, the amount you will invest later is small, but it is a good move for you. Since you regret investing this amount every month and maybe a little more next month, this buying style is not bad either. If you invest using DCA it will de-risk you a lot,
but you should always analyze the market, and it will be good for you. Also, you should know before investing that you only invest the amount of money you can afford to lose.
As long as @martinex have figured out the amount that he is using for regular DCA without it affecting other financial aspect of his life, he does not need to analyze the market. This is because he needs to focus on accumulating, and analyzing the market will be a distraction for him. Also we know that to analyze the market is difficult and no one can predict the next price movement of bitcoin, which always make most traders run at lost. He is not trading but hodling and building, which makes market analysis useless to him.
