Ethereum needs to stay above $3,085 to preserve its bullish setup on the daily chart, with that level identified as the support that must hold for the prevailing pattern to remain in place, analyst @alicharts said in comments carried by BlockBeats on Jan. 19. Price action continues to consolidate within a triangle on the daily timeframe, while daily active addresses have doubled over the past two weeks to more than 800,000, a sign that network participation has resumed its rise. Recent Ethereum ETF buying has been most concentrated between $3,119 and $2,772, a key support area for the market. If Ethereum maintains the $3,085 support and then clears the $3,400 resistance, the resulting breakout could open a path toward $3,660, with a subsequent move toward $4,000 also possible if those technical conditions are met, @alicharts said.

Bitcoin network hashrate fell below 1,000 EH/s on January 19, marking the first breach of that level since mid-September, Hashrate Index data show. The seven-day moving average stood at 993 EH/s as of last Saturday, down nearly 15% from the peak of 1,157 EH/s recorded on October 19. Leon Lyu, chief executive and founder of StandardHash, said in a Monday post on X that miners have been reallocating computing power from Bitcoin operations to AI computing services to pursue higher profit margins, a shift he described as the reason for the drop.

On-chain data analyst Murphy said on Jan. 19 that Bitcoin's options structure has shifted, with the $88,000 strike flipping from Long Gamma on Jan. 12 to Short Gamma, while the $90,000 strike remains in Long Gamma but its GEX dropped from $1.2 billion to $590 million, significantly weakening support in the $88,000–$90,000 zone. Murphy noted GEX at $92,000 climbed to $1.4 billion, a configuration that could amplify BTC price volatility. He added that URPD data show little change in coin distribution, with heavy positioning still concentrated between $87,000 and $92,000, the strongest current support band and hard to break. Murphy said if BTC were pushed below this range, the probability of price moving down to fill the lower gap would increase, with the midpoint of the double-anchor structure estimated around $72,000–$74,000.
