Cryptocurrency exchange OKEx has donated $4.5 million in Bitcoin (BTC) to its perpetual swap market insurance fund as a show of support for the Warren Buffett Power Lunch.
In a press release shared with Cointelegraph on July 23, the Malta-based crypto exchange revealed its contribution to the perpetual swap market insurance, whose amount is equivalent to what Tron’s Justin Sun paid to have lunch with Warren Buffett.
