MetaMask has disclosed its airdrop points calculation system on GitHub, highlighting that spot trading carries the highest weight. Users earn 80 points for every $100 in spot trading, compared to 10 points for the same amount in futures trading. Additionally, past trading of $1,250 can yield 250 points, with a cap of 50,000 points. Notably, transactions on the LINEA chain will receive a 100% bonus, effectively doubling the points earned.
