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.

The implied probability on Polymarket that Bitcoin will reach $100,000 in January fell to 25% on Jan. 19, down from 43% the previous day, BlockBeats reports. The prediction market is also pricing an 8% chance of Bitcoin rising to $105,000, a 21% probability of it declining to $85,000, and an 8% chance of it dropping to $80,000.

Bitcoin briefly fell below $92,000 on Jan. 19, with 24-hour liquidations exceeding $865 million, Decrypt reports. Lai Yuen linked the drop to renewed US–Europe trade tensions and tariff concerns, while Bitget analyst Ryan Lee said risk sentiment drove the move and sees support near $85,000 in late January.

Bitcoin's price fell below $92,500 amid growing concerns over a potential escalation in US-EU tariff tensions, according to The Block. The cryptocurrency had climbed above $97,000 earlier in the week, supported by exchange-traded fund inflows and institutional demand, before retreating alongside broader market risk aversion, The Block reported.

Centralized exchanges recorded a combined net outflow of 1,729.96 BTC over the past 24 hours, Coinglass data cited by BlockBeats show on Jan. 19. Kraken reported the largest outflow at 2,394.43 BTC, followed by Bybit with 395.37 BTC and Bitfinex with 62.33 BTC. Binance recorded a net inflow of 793.77 BTC during the same period, ranking first among exchanges by inflows.

If Bitcoin falls below $91,000 on Jan. 19, long-liquidation intensity on major centralized exchanges reaches $383 million, while a rise above $94,000 triggers short-liquidation intensity of $517 million, Coinglass data show. The liquidation map reflects cluster intensity rather than precise contract counts or values, with higher bars indicating stronger market reactions.
