Bitcoin (BTC) is rapidly regaining its lost dominance in the crypto market so far into 2023.

On Jan. 30, Bitcoin accounted for 44.82% of the total crypto market capitalization, the highest since June 2022. In September 2022, Bitcoin's dominance index was as low as 38.84%.

The index typically rises when most crypto investors reduce their exposure to smaller tokens and seek safety in Bitcoin. The reasons include Bitcoin's better liquidity and lower volatility than alternative cryptocurrencies, or altcoins, primarily in a bear market.

Bitcoin's market dominance to grow further?

As of Jan. 31, Bitcoin is up 38% year-to-date (YTD) at around $23,000. In comparison, the second-largest cryptocurrency, Ether (ETH), gained 30% in the same period, showing most investors remain gravitated toward Bitcoin so far in 2023.

From a technical perspective, the Bitcoin dominance index may rise further in the coming weeks as it reclaims its 50-week exponential moving average (50-day EMA; the red wave in the chart below) as support.

In doing so, the index could rise toward 48.5%, which has acted as resistance since May 2021. 

On the other hand, independent market analyst Rekt Capital sees the Bitcoin dominance index rising toward 46%, which coincides with the upper trendline of a giant descending channel pattern, as shown in the monthly-timeframe chart below.

The short-term bullish scenario in the Bitcoin dominance index chart appears in line with a similar upside in the spot Bitcoin market, with bulls eyeing a run-up toward $25,000.

Ethereum vs. Bitcoin th main driver of BTC dominance

The bearish argument is that the Bitcoin dominance index may start losing its upside momentum after testing its descending channel resistance, as it had done on several occasions in the recent past.

"Bitcoin Dominance is further overextending beyond red on the Monthly TF," notes Rekt Capital while citing the index's horizontal trendline support near 44.11%. The analyst adds:

"A Monthly Close above red could set BTCDOM for another dip into red which would benefit Altcoins."

The above analysis appears as ETH eyes a potential bullish reversal versus Bitcoin in the coming weeks.

Notably, the ETH/BTC pair has been consolidating near its support area (purpled) inside the 0.0676- 0.0655 BTC range since Jan. 24.

The ETH/BTC pair will likely see a rebound rally toward its descending trendline resistance (blacked) around 0.075 BTC if it continues to hold the support area. That, in turn, would reduce Bitcoin's "dominance" in the cryptocurrency market as Ethereum's share would rise toward 20%.
