Bitcoin mining company Riot has revised its $200 million Bitcoin-backed credit agreement with Coinbase to mitigate short-term price volatility risks. Key changes in the new agreement include switching the loan interest rate from variable to fixed, allowing a one-year credit extension, and introducing a "two-day rule" where stricter collateral requirements are triggered only if the value of the pledged BTC falls below a threshold for two consecutive days. Additionally, Riot sold 3,778 BTC (approximately $289 million) in the first quarter of this year and increased the number of restricted BTC used as collateral to 5,802.
