I tried this before, having a job while a day trader too. But it's hard to manage my time and I can't focus resulting to missed opportunity to buy/sell. It gives me headache and stress so I decided to stop and change my strategy.

Now i'm holding my crypto with a set target price when to sell. If the price didn't reach yet my desired amount to sell already then I will hold it for long.

If you can do both then why not? But it's important you can manage your time so you can do it well.
