Based on the real-time information, the future of cryptocurrency prices after ETF approval is a topic of speculation and predictions. Here are some key points to consider:

Bitcoin has experienced a rally of 61% since early October, largely driven by expectations of SEC approval for one or more spot Bitcoin ETF applications.

The consensus among experts is that spot Bitcoin ETF approval and the upcoming Bitcoin halving will be positive catalysts for the price of Bitcoin in 2024.

Nearly 90% of the Bitcoin supply being held is currently in profit, indicating growing anticipation of approval for a U.S. Bitcoin ETF.

Predictions for Bitcoin's price following ETF approval range from $42,000 to $100,000, with some experts suggesting a surge in price.

It is important to note that these predictions are speculative and subject to market dynamics and investor sentiment.

Overall, the approval of a Bitcoin ETF is expected to have a positive impact on cryptocurrency prices, particularly for Bitcoin. However, it is important to remember that the cryptocurrency market is highly volatile and influenced by various factors, so it is difficult to predict the exact future prices with certainty.
