I would say that now is not a good time to participate in test nets or bounties with missions like token swapping or similar tasks. The fees are high at the moment, and most of the projects are scams. In my opinion, the best time to engage in a test net is during a downtrend when the fees are more acceptable, so even if they scam you, it's not as significant. Currently, the best way to make money from the start is to participate in bounties involving sharing, posting missions, or buying some cheap new meme coins.
