20m investing half of my salary to bitcoin. DCAing every month.

I can say I’m fortunate enough to live in the household where I don’t have to pay for bills and such. I would take an advantage of what I can do with money and that’s bitcoin. Since December 2023 I have studied a lot about bitcoin. Bought bitcoin at 40k with all of my savings and hoping to hold for long as possible. Knowing I can invest more every month. My strategy is to invest half of my wage which is manageable since I don’t like spending on flashy and generic stuff, another half is to spend on food, a bit of stuff that makes me happy and such I would need in order to keep going. I put all the leftover from that half of wage from previous month and top it on future payslip. Am I stupid for doing this?
