According to news on April 19, the US dollar index closed down for four consecutive weeks this week, hitting a three-year low of 99.4, with a decline of more than 8% during the year. The weakness of the US dollar compounded by inflation and trade policy uncertainty has stimulated market demand for safe-haven and accelerated the flow of funds to gold and non-US currencies. Gold surged 2.76% this week, hitting a record high of 3,357.68 US dollars per ounce. U.S. stocks were under pressure simultaneously. Dow Jones and Nasdaq fell more than 2.6% weekly. The Federal Reserve Board's statement that it would not bail out the market further exacerbated market tensions. Under the dual pressure of the US dollar and the stock market, the potential of crypto assets as alternative hedging tools has once again attracted attention. Bitunix analysts suggest that if gold continues to strengthen and the US dollar index continues to weaken, mainstream cryptocurrencies are expected to welcome capital inflows. The short-term critical range of BTC is between US$83,000 support and US$86,000 pressure. If it successfully breaks through, it is expected to challenge the US$90,000 integer mark and launch a new round of upward market.
