As dYdX’s governance token (DYDX) gains amid speculation that Chinese traders could be migrating to the derivatives decentralized exchange (DEX), savvy decentralized finance farmers are claiming to be sitting on six-figure stashes after gaming the protocol’s recent airdrop.

DYDX has gained 85% in two days as reports claim that China’s crypto traders are converging on the decentralized margin trading protocol as Beijing moves to further crack down on digital assets.

The exchange’s governance token was airdropped to users on Sept. 8. As the number of tokens received by users was determined by historic trading activity on the exchange, news of the airdrop drove a flurry of activity as farmers flocked to the platform to capitalize on the free tokens.

With the DYDX token currently trading at $21 and its market capitalization surpassing $1 billion, many airdrop recipients have made off with significant profits.

Some users have taken to Twitter to boast of their airdrop earnings, describing how they sought to game the protocol by trading the same assets on the platform between multiple wallets under their control to qualify for hundreds of thousands worth of rewards.

Twitter user Daniel Que tweeted that his airdrop is “worth $420K now,” noting that he would have been excluded from the event if he were still residing in the United States.

“Moving to Taiwan (and not getting a Green Card) was a good call,” he said.

Others were not so lucky, with many users complaining about having been “protected” from the airdrop by the United States Securities and Exchange Commission.
