REimagined 
FInance)  Touted as "Defi Reimagined," ReFi is a financial service on both Ethereum and Binance Smart Chain that offers users a variety of yield farming opportunities.  Introduced in 2021, ReFi token holders choose risk levels.  Low risk means low-volatility assets such as stablecoins.  Medium-risk customers invest in liquidity pools that generate trading fees and high-risk means long-term speculation.  ReFi Pro provides asset management for institutions.
Participation requires purchasing a minimum amount of $REFI tokens on decentralized exchanges, which represent a percentage of ReFi's cash flow.  Profits in ETH, BNB or additional $REFI can be claimed routinely by token holders.  See
