Bitcoin (BTC) and Ethereum’s native token, Ether (ETH), started the week on a depressive note as investors braced themselves for a flurry of rate hike decisions from central banks, including the U.S. Federal Reserve and Bank of England.Bitcoin price fails to hold $20,000On Sep. 19, BTC’s price has failed to regain the $20,000 psychological support zone. The BTC/USD pair slipped by 6.5% to around $18,250, while ETH dropped 4% to approximately $1,280. Their gloomy performance came as a part of a broader decline that started in mid-August, wherein BTC and ETH wiped a total of 28% and 37% off their market valuation, respectively.BTC/USD and ETH/USD daily price chart.

Last week, MSCI’s flagship global equity index, ACWI, which combines developed and emerging market stocks, fell 4.25% to nearly $84. At its peak, the index was trading for $107.39 in November 2021. Interestingly, Bitcoin and Ethereum peaked in the same month at $69,000 and $4,950, respectively.ACWI weekly price chart.

The global macro environment supersedes everything. If the global markets were generally bullish, then the Merge would have resulted in a pump. But it didn’t.This goes for #Bitcoin as well.— Kevin Svenson (@KevinSvenson_) September 18, 2022Instead, investors may seek safety in low-volatile assets, including the U.S. dollar and government bonds.For instance, the U.S. dollar index, a barometer to measure the greenback’s strength, rose by 0.5% to 110 on Sep. 19 after its highest weekly close since 2002. Similarly, six-month U.S. Treasury notes yield 3.79% if held until maturity, thus offering investors a safer investment alternative with guaranteed returns in the short term. Similarly, the U.S. 10-year Treasury yield has surpassed its June high when Bitcoin dropped to yearly lows. U.S. Treasury Yields as of Sep. 19.

MACD_D, a user at the on-chain analytics platform CryptoQuant, argues that this is typically bad news for the price of Bitcoin.”If the holder, which held BTC in its seventh year, moves more than 5,000BTC, there could be a strong downward trend in the future,” the verified user wrote, stressing: “This indicator showed signal 7 in the past and fell 6 times except for 1 (07 Feb ’21) The fact that the long-term holder moved the BTC means that there will be an unusual price movement in the future.”Bitcoin spent output age bands (7-10 years).

Excerpts:”When #BTC is simply transverse, the excessive rise of Ethereum creates a bubble. In particular, if the ETH dominance rises by more than 20%, it provides a good timing to enter the short position.”Related: Goldman Sachs’ bearish macro outlook puts Bitcoin at risk of crashing to $12KFrom a technical standpoint, Bitcoin has entered the breakdown stage of its prevailing “bear flag” pattern, now eyeing an extended decline toward the flag’s profit target at around $14,500 in 2022.BTC/USD daily price chart featuring bear flag breakdown setup.

As a result, ETH price could drop toward $750 if the bearish continuation pattern plays out, along with weakening technicals for the ETH/BTC pair as well. ETH/USD daily price chart featuring symmetrical triangle breakdown setup.
