将 Rai Reflex Index RAI 兑换为 United States Dollar USD

Please note: Whilst this token may be described as a ‘stable’ asset its value is not designed to be pegged to any fiat currency (e.g. Pounds Sterling or US dollars) and its price may therefore fluctuate. This token relies on complex algorithmic arrangements and is collateralised by Ether (ETH), meaning its value could decline or become volatile. Please visit https://www.coinbase.com/asset-risks for more information on asset risks. RAI is an Ethereum token. The RAI-USD exchange rate is determined by supply and demand while the protocol that issues RAI tries to stabilize its price by constantly de- or re-valuing it. The supply and demand mechanic plays out between two parties: SAFE users (those who generate RAI with their ETH) and RAI holders (those who hold, speculate on or use RAI in other protocols and apps).
