The post-ETF euphoria that characterized the crypto world is subsiding. Bitcoin's recent fall continues, sinking to its lowest point since early December. As of Tuesday, the cryptocurrency was hovering around $38,767.10, marking the first instance of it dipping below $40,000 this year.In the wake of the launch of spot Bitcoin ETFs in the United States on January 11th, the cryptocurrency has experienced a significant 15% drop. Market analysts attribute this decline to short-term selling pressures primarily driven by exits from the Grayscale Bitcoin Trust (GBTC). Meanwhile, other ETF products, such as BlackRock's iShares Bitcoin Trust and Fidelity's Wise Origin Bitcoin Fund, have witnessed an influx of investment capital, approximately $1 billion each.Despite the substantial outflow from GBTC, analysts believe the overall impact to be minimal as the combined inflows into other ETFs have more than offset the outflows by around $1.2 billion. However, the psychological effects of these large daily outflows from GBTC appear to be influencing the market.Before the introduction of Bitcoin ETFs, investors anticipated this correction. The expectation began to intensify in August, leading to a steady appreciation in Bitcoin's value. What Does This Mean For Me?Analysts predict a further downward trajectory for Bitcoin before it can reverse and move higher again. In the short term, $36,000 is being closely watched as a potential support level.The downturn in Bitcoin has also dragged the rest of the crypto market lower. Ether dropped by 5%, Solana shed 7%, and the tokens associated with Uniswap and Ripple's XRP declined by 5% and 6%, respectively. Dogecoin also experienced a 6% loss.
