Even after learning how DIY investing into stock market works, is there a good reason still for using robo advisors?

I do trade on a daily basis but I do have a few robo advisors as well. I intend for the robos to have a more stable and slow wealth accumulation with its diversified portfolio, while trading allows me to take riskier positions and more aggressive individual stock picking (which also means more volatility). You can consider allocating funds into both as the robos are easy to set up and you can let it run on the side - I started investing with the robos in June 2020 and they are offering pretty good returns of 10-15%.

I used both

DCA into robo-advisors (time in market)

DIY individual stock (timing the market)
