$BNB After three long days of continuous mining, I used 300 BNB to mine 423 BIO. The borrowing cost was about $1.5 each (I have stopped borrowing for mining this time and bought 18,000 BIO at $0.63 before the whales' trading). According to observations, the current borrowing rate for BNB is about 30% annualized, which is similar to my borrowing costs from the past two days. Currently, the pre-market price on some second-tier exchanges is about $0.87
