Pankaj Balani, CEO of the crypto derivatives exchange Delta Exchange, said that bitcoin is vulnerable to falling further because buying demand is absent. “We are not seeing any bottom fishing at these levels, and the interest to own bitcoin risk around $40,000 remains low,” Balani told CoinDesk’s Omkar Godbole in a WhatsApp chat. “We could retest $40,000 and should that break, we can see a fresh round of selling come through.”
