Odaily Planet Daily News Tron DAO Reserve withdrew about $750 million worth of Bitcoin on Wednesday, which was previously used to support the USDD stablecoin. Tron founder Justin Sun said users don't need to worry, explaining that the move was to improve capital efficiency because USDD's previous long-term collateralization rate exceeded 300%. USDD is currently mainly supported by Tron's native token TRX. Sun compared USDD's mechanism to Maker DAO's DAI, emphasizing its security. Currently, USDD has a circulation of about $744 million, making it the seventh largest stablecoin. Although official data shows that its collateralization rate exceeds 230%, third-party agency Bluechip estimates that the actual collateralization rate may be only 53%. (The Block)
