Odaily News Vetle Lunde, head of research at K33 Research, said in an interview that open interest in futures contracts on the CME derivatives exchange hit a record high. This is how most U.S. institutions currently buy Bitcoin futures contracts. But many traders have been waiting for spot Bitcoin ETF options on major exchanges such as the New York Stock Exchange and Nasdaq because it can enhance liquidity and provide hedging tools. Lunde said that demand for leveraged long exposure to Bitcoin and Ethereum is climbing, and VolatilityShares' BTC exposure hit a record high. (CNBC)
