The Bitcoin price continues to decline, pushing deeper into a bearish phase as investor sentiment shifts towards capitulation. A recent on-chain analysis has shed light on the factors influencing Bitcoin’s typical price movements during December, a period often marked by volatility.
A significant observation comes from the Coinbase Premium Index, which has recently dipped sharply. This metric assesses the price differential of Bitcoin traded on Coinbase in comparison to other major exchanges like Binance. A declining Coinbase Premium indicates a growing selling bias among US investors, which correlates with the recent downturn in Bitcoin’s value.
According to the crypto research group XWIN Research Japan, this decline in the Coinbase Premium began in late November and has persisted into December, marking a pivotal shift in market sentiment. Historical analysis shows that December typically brings weaker Premium readings. These dips are often attributed to year-end rebalancing and tax-loss harvesting by institutions and individuals in the US.
However, deviations from this trend have been noted in previous years. In 2018 and 2022, significant downturns in the Premium coincided with broader market stress. Conversely, both 2020 and 2023 witnessed positive Premium readings positively correlated with a bullish market sentiment at those times.
This year’s December scenario, however, has presented a “unique twist.” Despite starting the month with negative Premium levels, there has been a swift recovery into positive territory. This rapid rebound suggests that the Bitcoin market might be facing decreasing bearish pressure, potentially signaling that the market is approaching a local bottom.
XWIN Research emphasizes that the future stabilization or continued downturn of Bitcoin prices will largely hinge on upcoming US capital flows, derivatives positioning, and the trajectory of premium trends. At present, Bitcoin is valued at approximately $89,321, with little significant movement observed over the past day.
As market dynamics evolve, investors are keenly watching for indicators that could suggest a recovery or prolonged decline in cryptocurrency prices.
