In April 2023, Binance launched a series of airdrop activities in the Alpha sector (such as ZORA, DOLO, GM, etc.), essentially leveraging high yields to attract user participation and enhance platform activity and ecological stickiness. The airdrop rules are simple (for example, trading $50 can earn thousands of tokens), which stimulates users to increase their trading volume in the short term, but also raises controversies: for instance, ZORA is positioned as a 'functionless' meme coin and is questioned whether the team is using airdrops to harvest traffic, deviating from the technical narrative. Although such activities create a win-win situation for exchanges and project parties, excessive reliance on airdrops can breed speculative bubbles, potentially undermining the long-term value foundation of the tokens.
