What is the circulating supply of REI network?

Excuse me, could you please elaborate on the circulating supply of the REI network? I'm particularly interested in understanding the current availability of REI tokens in the market and how it may impact the overall value and liquidity of the network. Could you provide some insights into the factors that determine the circulating supply and how it differs from the total supply of REI tokens? Additionally, how does the circulating supply affect the price and trading volume of REI tokens on various exchanges? Thank you for your attention to this matter.
