Try Quests to earn cryptoLuna Staking Yield
Luna staking yield comes from transaction fees on the Terra blockchain (some calculations like that displayed on Terraswap also includes ANC/MIR airdrops). Transaction fees on Terra consist of gas and a tax. For swaps using Terra's market protocol function, there is an additional spread fee, which increases in times of market volatility. Below we can see the yield of Luna staking over the past 30 days, plotted against the Luna price. In general we can see an inverse correlation between price of Luna and staking yield. Luna staking yield comes in a variety of different currencies (Luna, stables, SCRT etc). The simple explanation of this inverse correlation is that the value of this staking income falls relative to the value of staked Luna as Luna price rises, meaning the APR falls. Another factor contributing to this will be the spread fee. In periods of high market volatility e.g. a Luna price crash, the spread fee will increase on market swaps from the Terra station, increasing staking yield.
