Metamask's little fox can check for airdrops now. When farming, I predicted I could earn a few dozen dollars, but I almost got half of it back. Later, with a fourfold points promotion, I felt it was over, and indeed it was.
This account invested 600 dollars, and I estimate it can sell for 200 dollars in the end. That means the little fox made a 70% service fee this time, pure profit, but I only did one account.
