I forget where on Reddit I saw this, but it was a pretty good discussion about anti-piracy for indie devs. I think it was r/gamedev
Basically, the amount of time you spend on trying to implement a DRM or anti-piracy measure would probably be much better spent doing something else with your game like marketing or a new feature or bug testing.
If AAA studios ~easily~ get their drm measures bypassed, without a doubt yours would too. Fast. And it isn't like something that would even stall pirates, especially coming from an indie dev.
Even greenlit games get bypassed fairly easy.
