The essence of DCA is to eliminate the tendency of investing under duress such as forfeiting your basic needs so you can buy bitcoin. This might not be the best approaching as it can drain you psychologically and even deny you peace of mind. The reason for accumulating wealth is for the peace and comfort it brings, this means that any method you are adopting that does not give you this peace can never be regarded as DCA. Howbeit, we can make acceptable sacrifices to be able to secure the future but we should be able to have some limits.
When you hear DCA, the first thing that should come to your mind is buying Bitcoin in a way it will not affect your urgent needs. Like JJG have said, DCA can help you manage the problem of overinvesting because it does not require buying at bulk
I don't really agree with this because basically when we talk about DCA I think the pressure is still there and one of the psychological factors about greed is still very big and of course we also have to have a big reference in consistency which I could call it a pressure that we have to be aware of.
But on the other hand DCA clearly makes us more comfortable in investing because we don't need to feel that we are burdened with the existing pressure and that's what makes me personally suggest DCA as one of the right strategies for us to live with, especially for beginners and people who have modest income.
