The blockchain-based yield program Doubler v2 has successfully taken residence on Manta Pacific, offering users an innovative storage and retrieval method. Users can deposit ETH, MANTA into the platform to earn returns from the Martingale trading strategy. Recently, the total value locked (TVL) in the MANTA pool is $120,000, with a yield annual percentage rate (APY) of 49.64%, while the TVL in the ETH pool is $382,000, with an APY exceeding 10%. To attract more users, Doubler v2 also launched a DBR airdrop campaign and set up an early bird reward mechanism. By utilizing the low-threshold blockchain Martingale trading strategy, Doubler v2 achieves the separation of principal and earnings. Users only need to deposit assets to obtain Token-1-C, representing the principal, and Token-1-10x, representing a 10-fold return. When the price drops, the Martingale strategy utilizes the funds pool for additional purchases, reducing the average holding cost for all users; conversely, during a price rebound, it generates additional excess profits.
