How can I know about the $SPA raid airdrop? I saw a raid airdrop at ten o'clock last night, but I didn't have enough points to claim it. I saw that some friends can use certain bots to detect the on-chain transfer of coins. Is this monitoring for specific addresses? For example, if the official releases an airdrop announcement, can we monitor the corresponding address? If Binance doesn't notify in advance, can we still detect signs of a large amount of incoming coins on-chain preparing for an airdrop?
