The U.S. dollar index (DXY) could continue its slide in Q4, according to a classic technical setup known as a “rising wedge.” The greenback’s bearish prospects may boost Bitcoin’s (BTC) price to new all-time highs as it holds above $62,000.DXY poised for another 1.75% dropRising wedges are bearish reversal patterns that begin wide at the bottom but contract as the price increases. As a result, the trading range narrows, which makes the rally unconvincing. That typically prompts the price to break below the wedge’s support line and later fall by as much as the maximum distance between the pattern’s trendlines.The DXY has been forming a similar price structure since August. Moreover, the index’s decline this week had it break below the wedge’s support line, therefore triggering a bearish setup toward 92.416, down about 1.75% below the level of breakout (around 93.98).DXY daily price chart featuring rising wedge setup.

Instead, their focus has shifted toward policy normalization elsewhere, including the United Kingdom, where analysts have forecasted rate hikes worth 35 basis points by the end of this year.Bitcoin rallies on ETF FOMOBitcoin price found support from the weaker dollar this week, in addition to optimism about the debut of the first exchange-traded fund (ETF) tied to BTC futures on the New York Stock Exchange.BTC/USD has rallied by over 40% month-to-date to hit a five-month high of $62,987 on Oct. 19.

Tom Lee, co-founder of Fundstrat Global Advisors, said in a note on Oct. 18 that ETFs based on Bitcoin futures would together attract more than $50 billion in inflows in the first year, adding that BTC could conceivably rise to $168,000 in response.Related: BTC price is up 50% since China ‘selflessly’ banned Bitcoin miningJurrien Timmer, director of global macro at Fidelity Investments, noted that Bitcoin would become a six-figure asset by 2023, citing Metcalfe’s law, which measures a network’s value based on its growth rate.“Other technology innovations, and even, like, a stock like Apple — not that I’m a security analyst — has gone through that same process, where its sales go up 38-fold over 10, 20 years, and its market value goes up by 900-fold,” Timmer told Yahoo Finance, adding:“So it’s an exponential increase. And based on those metrics, by 2023, my models show $100,000.”The views and opinions expressed here are solely those of the author and do not necessarily reflect the views of Cointelegraph.
