In mid-April, funds turned from outflow to inflow, and BTC soared from $60,000 to $67,000.

In early May, BTC soared from $57,000 to $65,000.

In these two months, ETF funds often change prices in advance, but the inflow and outflow of ETF funds has become a reverse indicator.

In early May, there was a large outflow, but it hit the low point, indicating that institutional funds will drive price fluctuations, but will also use panic and greed to make the market passively liquidate.

The turning point of funds is more referenceable. For example, the inflow of ETF funds again in the past two days is a good thing for the weak spot.
