USDD is a new algorythmic stablecoin, it works similar to TerraUSD. Both are algorythmic stablecoins, both are minted by burning their network's token (USDD by burning Tron (TRX) and UST was minted by burning LUNA), both offer huge interest rates (UST's anchor protocol offered 20% APR and USDD offers 30%) which is super suspicious (haha sus amogus). Tron TRX is already a scummy chain and USDT Tether is minted there plus Justin is known for being an asshole and a scammer.
