Recently reviewed the order earnings for December, totaling 766u, which is a bit more than the 600u in November. I calculated this in detail to understand how this number was achieved.

The main contributor is the trading competitions. The four competitions contributed: 110u profit (with an investment of 60u), 75u profit (with an investment of 20u), 140u profit (with an investment of 70u), and 150u profit (with an investment of 50u). Plus, a pure profit of 100u from a recharge task, bringing in a total of 375u from these items.

Airdrop tasks are also significant. In December, I participated in about 8 airdrops, averaging 40u each, contributing a total profit of 320u. Combined with the previous parts, this sums up to 695u.

As for the "score boosting cost" that some people are curious about, it actually refers to the investments in the trading competitions mentioned above—60u, 20u, 70u, 50u. These are the necessary expenses for participating.

There are also other scattered incomes from trading competitions on certain chains (though not very profitable), various spot tasks, recharge rewards, and financial products, which together add up to a few tens of u. The final figure of 766u roughly matches this. In other words, diversifying participation across different types of tasks creates a substantial monthly income.
