I've taken a fresh look at cryptocurrency airdrops. Actually, these distribution methods for such projects have a pretty interesting history. They are a technique used by blockchain startups to promote new tokens, and 2021 was truly the peak of airdrops. That year alone, 18 out of the top 50 airdrops were executed, compared to only 5 in 2020. Afterwards, in 2022 and 2023, the trend declined due to the market downturn.

Now, let’s take a look at some of the largest cryptocurrency airdrops. First, Uniswap was dominant, distributing $6.43 billion worth of UNI in September 2020. Its all-time high (ATH) reached about $44.92. This event became a symbol of the DeFi summer.

Next is ApeCoin, which distributed $3.54 billion worth of APE in March 2022. The ATH was $26.70. Participants in the Yuga Labs ecosystem received rewards worth up to $258,737, effectively giving away NFTs for free.

dYdX is third, with a scale of $2 billion. However, this was a multi-year vesting schedule, so the full amount wasn’t available all at once. Its ATH was $4.52.

The biggest airdrop of 2023 was Arbitrum, which distributed $1.97 billion worth of ARB in March. The ATH was $2.39. Since it was 2.9 times larger than Optimism’s, it had a significant market impact. In fact, Arbitrum’s TVL increased from $1.49 billion in January to a peak of $3.68 billion in May, a 147% rise.

Including ENS, Internet Computer, Bonk, Celestia, LooksRare, and 1inch Network, looking at these cryptocurrency airdrops shows how diverse project growth strategies can be. ENS raised $1.87 billion, ICP $30M, Bonk $1.33 billion, Celestia $730 million (ATH $21.13), LooksRare $712 million, and 1inch Network $671 million.

By examining these airdrops, you can see how projects are innovating in user engagement. It’s not just about distribution; there are strategic designs like positioning tokens as governance tokens or targeted allocations to specific contributors. As markets fluctuate, these methods continue to evolve.
