The optimism of $ 40,000 subsides
Data from Cointelegraph Markets Pro and TradingView showed that BTC / USD reversed to $ 38,250 after losing over $ 4,000 in a few hours.

Traders, who had $ 39,000 at the time of writing, were confused by an unexpected fall that came just as BTC reached several-day highs above $ 43,000.

Thus, the closure of the trading platforms was predictably large. For Bitcoin and altcoins combined, the 24-hour position distribution is $ 725 million, while BTC positions are $ 292 million.

The vast majority of losses were in long positions, indicating that the area around $ 40,000 has created significant credibility as a strong guideline.

As Cointelegraph reported, options expiration on Friday, including open interest rates of nearly $ 600 million, was seen as the main driver of volatility. In contrast, external triggers, such as Russia’s proposed total ban on cryptocurrency trading and mining, appear to have little effect.

“$ 42.4K- $ 42.7K could not continue to hold bitcoin, so it was a nuclear trend to the other side of the region and most likely a continuation of more downward momentum and a lower bottom,” explained Cointelegraph contributor Michael van de Poppe . . .

The move was long overdue as more conservative analysts predicted returns closer to $ 30,000 or even less during January.

Ether returns to a solid foothold
Meanwhile, altcoins have suffered noticeably more from the fall of bitcoin.

Among the top 10 cryptocurrencies by market value, a fall of 10% was common and the decline was limited, with only Terra (LUNA) able to limit losses below 5%.
