Personally for me it was doing my job, I also went down the rabbit hole of trying to earn sats here and there but in terms of trading time for the most sats, I found that working was the best and then converting that into bitcoin.

If you can't work full time, I get that and you're better off trying to do jobs on freelance sites and then getting cash, lets say completing tasks on upwork, taking the cash into paypal and then selling it P2P for bitcoin

There are some native bitcoin freelance apps that offer micro tasks like stakwork and microlancer and pick up a few sites
