The Stablecoin Supply Ratio (SSR) is the ratio between Bitcoin supply and the supply of stablecoins denoted in BTC, or: Bitcoin Market cap / Stablecoin Market cap. We use the following stablecoins for the supply: USDT, TUSD, USDC, USDP, GUSD, DAI, SAI, and BUSD. When the SSR is low, the current stablecoin supply has more "buying power" to purchase BTC. It serves as a proxy for the supply/demand mechanics between BTC and USD. For more information see this article.
