Capitulation?
Most people only look at what happens in the short term, and missing the bigger picture.
Despite recent news about capital outflows from Bitcoin ETFs reaching $4.4B or $1.72B, as you mentioned. Many people fail to notice that the total assets under management in BTCETFs still stand at more than $102B. $4.4B is only around 4% and $1.72B is just 1.5% of that $102B.
So there is no sign of capitulation here, and there is nothing worth paying too much attention to.
