$BTC rebounded in the evening, while $SAND continued to fall. For SAND holders waiting for Bitcoin to recover so they can break even, this divergence is worth noting.

From 16:00 to 19:00 Beijing time on October 18, comparing hourly closing prices, BTC rose about 0.5%, while SAND fell about 5.9%. SAND closed lower for three consecutive hours, and its weakness persisted for several hours.

I'm cautious about SAND in the short term: Bitcoin has rebounded, but SAND hasn't followed. The specific reason for the decline is still unclear, and these prices alone don't prove that anything negative has happened with the project. But if you're adding to your position solely because “Bitcoin is up, so SAND should be too,” the current trend doesn't support that reasoning. I'd wait for SAND to show signs of improvement before considering increasing my holdings.
