Not just 400, is it?

Now earning points to get airdrops, the risk far outweighs the rewards. If you buy in with good luck, you might sell shortly after with minimal loss, but if you're unlucky and casually spend 512U, you could end up losing 2-3U with just a few attempts. Using 2048U to earn points is fast, but it significantly increases the risk; you might have 9 times of small losses or even small gains, but doing this every day, how can you avoid getting wet when walking by the river? If you encounter a spike once, you could directly lose 100-300U, and unfortunately, some have already faced this. If you want to get airdrops, you must spend 4096U every day; double points means 13 points, totaling 225 points in 15 days. Even if you earn enough points, taking an airdrop deducts 15 points, and at most you can stretch it to 3 times of 300U in a month. So if the platform points are still around 200 or even higher later, it might be better to just give up. It's more worthwhile to find a few low market cap orders below 5 million to catch spikes; such operations can yield a few hundred U in a month, and the risks are also low.
