Bitcoin and Ethereum have seen gains of 3.4% and 2.43% respectively in the last 24 hours, following the release of the latest US Consumer Price Index (CPI) data. Despite the market's uncertainty, there's been a significant shift in sentiment among retail traders on Binance, with 70.25% of accounts holding net long positions on Bitcoin, up from 57% just a day prior.

This bullish behavior comes amidst ETF outflows, indicating investor caution. Grayscale's GBTC saw the largest net outflows of $121 million, followed by ARK Invest's ARKB and Bitwise's BITB, with outflows of $65.5 million and $11.7 million respectively.

Lower inflation figures are expected to further boost the crypto market. The CPI remained essentially unchanged in May, with an annual increase of 3.3%, slightly below predictions and April's 3.4%. The latest price movement and retail long position suggest that BTC has already priced in the latest CPI data and the upcoming Federal Open Market Committee (FOMC) decision.

Overall, the market sentiment remains optimistic despite the uncertainty, with retail investors showing strong belief in a potential rebound.
