Pain for Bitcoin and altcoin investors as well as a new cascade that saw the $40,000 support disappear.

Market Update
Bitcoin (BTC) is lower on Friday after an overnight wave of volatility sent the largest cryptocurrency to a six-month low.

40,000 dollars liberated optimism
Data from Cointelegraph Marketplaces Professional and TradingView shows BTC/USD reversing at $38,250 after dropping more than $4,000 in the hour.
Swinging around $39,000 at press time, traders are reeling from the sudden drop, which occurred just as BTC hit a multi-day high, surpassing $43,000.
Liquidations on trading platforms therefore have predictive implications. For Bitcoin and altcoins in total, the 24-hour position unravels a total of $725 million, with BTC positions accounting for $292 million.
The majority of casualties were in long positions, a sign that the area around $40,000 has attracted considerable confidence as a solid support line.

As Cointelegraph reported, Friday’s option expiration, which involved nearly $600 million in open interest, was seen as the main culprit for the volatility. In contrast, external triggers such as Russia’s proposed mass ban on cryptocurrency mining and trading appear to have had little or no impact.
“$42.4-42.7K failed to hold Bitcoin, hence a kernel towards the other side of the area and most likely, a continuation towards further downward momentum and lows” more -> happened”, Cointelegraph contributor Michaël van de Poppe explain.
The move has been around for a long time, with more conservative analysts predicting profits to be closer to or even below $30,000 throughout January.
Ethereum Returns to Established Support
Altcoins, meanwhile, were hit significantly harder when Bitcoin fell.
Among the top ten cryptocurrencies by market capitalization, 10% declines are common and resilience is limited, with only Terra (LUNA) dropping losses below 5%.
