Why does Bitcoin only drop on Monday, while it can hold up over the weekend? That's a good question. It may seem contradictory, but there's a behind-the-scenes explanation.

It's true that the US stock market is closed on weekends, but you need to pay attention — the futures market doesn't stop. The Nasdaq 100 futures (NQ) and S&P 500 futures (ES), two key indicators, are traded over the weekend as well. Last weekend, these two instruments plunged, and only by Monday's open did Bitcoin follow suit and move downward.

This is no coincidence. If you regularly analyze candlestick charts and corresponding event timings, you'll notice this pattern has occurred many times over the past year. The fluctuations in US stock futures can essentially predict the market trend for cryptocurrencies on Monday — acting like an invisible signal light.

At its core, this reflects the logic of global capital flows. US stock futures represent institutional investors' expectations for Monday's opening. When futures fluctuate significantly, it indicates that risk assets are under pressure overall. As the most sensitive among risk assets, Bitcoin naturally follows suit on Monday.

So next time you see US stock futures move over the weekend, consider preparing in advance. History repeats itself, but the details always differ.
