you can't really trust users nowadays, claiming without completing their task? but it should reflect on the system that they haven't completed the task so they have no way to claim what is not for them. $0.01 is really very small, it might not attract some freelancers to even check the task. do you think people will be interested on checking specific tasks if they see that it is only worth $0.01?
Yes, recently I had a task, I did it for test purposes, I paid $0.1 for downloading app, and I had 4 downloads, while as completed task there were 10+ submissions
Some of them were without screenshot (so I understand they didn't complete the task), but some with screenshot and as I understood later some just resent screenshot, but still I paid may be to 8 contracts, while I got only 4 downloads... (or even less as I asked also some friends to join with that link)
What I need to say, I don't mind loosing few cents, but to loose $0.5 or so it's not good
As I planned to have bigger tasks for 100 and more people
And I think they don't need stablecoin, there are options to pay in other coins now
