DCA is a smart strategy in every circle, so far you're earning income you don't need to wait for dip before buying because you believe that on the long term you will be profitable. Every investors that believes in the potentials of Bitcoin to always Hit ATH will not bother about current price at anytime of accumulation. Very rich people can afford to wait for dip because they have surplus funds and when it happens they will buy in lump sum but for the average income earners who don't know how long they have to wait is better for them to buy when they have the funds.
If you really do believe you will make profit on the long term, then you are going to definitely make a lot of money. If you do handle a lot of money, then it's a risk and you are going to be worried for sure. Obviously what is "a lot" changes depending on your own wealth, basically what I mean is that if you are putting more money than you should, or money that is your entire savings, you are going to be super worried because that's all you have and you are worried about losing it.
That's not easy and takes time to get used to it. For me it has been 10+ years and I have been doing fine and not anxious about it anymore because I got used to it, but I do remember in early days, every small drop in price would get my heart in my mouth.
