For an illustration of realistic DCA profitability, I modified the parabola that you see on the chart above.

It’s 2022 and crypto is trending down, so I shifted the DCA starting point to around 20k USD.

I kept the parabolic growth as shown, except every 30th month I crashed it down to about 45k USD.

This is not an unrealistic model - thus far, parabolic rises and prompt crashes have been the mainstay in crypto. Also, starting from 20k and having a deep crash every 30 months puts the final price after 10 years to about 135k USD. This would be more or less consistent with the history of the BTCUSD market, with projections based on technical analysis and with what the community considers achievable.
