CoinMeta data: According to U.Today, as the US Dollar Index (DXY) soars to 18-month highs, the selling pressure on Bitcoin has become increasingly evident. Currently, the trading price of Bitcoin is around $82,490, down 1.62% in the past 24 hours and 4.61% in the past week, with a market value of nearly $1.65 trillion. The opening of a large number of short positions indicates weak spot demand, and there has not been sufficient buying pressure in the spot market to reverse the short position situation. On the 15-minute chart, DXY shows an even more aggressive upward trend, rising from 102.12 to 102.55, breaking through the key psychological barrier of 102.50. Due to rising oil prices, major oil importers (especially Europe and Japan) have been affected, leading to a depreciation of their currencies against the US dollar. In addition, the increasingly hawkish monetary policy prospects of the Federal Reserve are also contributing to the strengthening of the US dollar. The US CPI data to be released on Wednesday will be the next key catalyst and may have a significant impact on market expectations for the Fed's next round of policy actions.
