Trade in the Binance Alpha market, trading around 50-100 oil each time, trade daily to receive Binance airdrops, earning 1000-2000 oil in a month.

I tried it, and it indeed exists, and Binance has announced it.

If you have some free time, you can trade a few times; earning 1000-2000 oil a month is still acceptable, enough for living expenses.

Of course, this won't be the norm; while it's still available, go ahead and take advantage of it. It's similar to how Didi initially spent money to expand its market. Once everyone forms a habit or if the traffic is sufficient, it will no longer be available.

Of course, if this can continue indefinitely, it would be a good thing for us, equivalent to the earnings from delivering food.

Just go for it; it's not like we don't have the capability!
