BTC has been fluctuating here for four to five days, and unexpectedly rallied on Sunday

(It may also be stimulated by positive news from the futures market)

It's showing a relatively strong fluctuation; the short leverage accumulated here is almost enough, so a spike upwards is reasonable.

Another point is that the accumulated funds for Bitcoin are still present, but Ethereum has basically escaped, so the rebound for ETH lacks strength...

Currently, I still hold a bit of a base position, waiting for a better opportunity, and will follow up for confirmation after leaving the range.
