The crypto market remained steady on Friday, with bitcoin BTC trading at $71,700 and ether (ETH) at $2,180. Daily Bollinger bands, a technical analysis tool that measures market volatility, are at their narrowest since early 2024. The U.S. consumer price index (CPI) data is expected to influence the market, with high inflation figures typically boosting the dollar's dollar. Open interest (OI) in bitcoin futures increased by 1%, with average perpetual funding rates on major exchanges at their highest since Feb. 4. Other major cryptocurrencies were mixed, with OI increasing slightly in XRP (XRP), while OI holding flat in ETH, and solana (SOL). Privacy-focused ZEC showed OI growth and negative rates, indicating traders are continuing to short futures and hedge downside risks. The 30-day implied volatility index, BVIV, has slipped to 45%, indicating market calm. The decline in volatility is largely led by ETF-related flows.
