Over the past 2 years, I have completed about 100 projects in the test network, but the profit received, which was paid by only a few projects, is much less than what was received from Optimism alone. It is possible that after launching on the main network, this participation will be an additional bonus when distributing airdrop, but for myself I decided that I would no longer perform tasks on the test network, since this is just a waste of time.
