According to @EmberCN, a whale or institution sold 10,414 ETH last night. The ETH was transferred to Binance from three addresses, and $36.32M in stablecoins was withdrawn from Binance. This sale was part of a strategy to reduce leverage, as the whale or institution had collateralized 68,300 ETH ($228M) on Aave and Compound to borrow $141M in stablecoins.
