Bitcoin spot volume collapsing 81% looks scary on the surface, but historically this kind of dead market activity often shows up near the end of corrections, not the beginning. The same thing happened in 2023 before BTC reversed and started trending higher again. What stands out to me is that despite weak trading activity and ETF outflows, the overall institutional structure still looks strong. ETFs still hold massive amounts of BTC, and there's no sign of panic selling yet. Low volume also means liquidity is thin, so once momentum returns, price moves can become very aggressive in either direction. If ETF inflows come back, BTC could reclaim strength surprisingly fast. Personally, I see this more as a cooling phase than a market collapse. I'd stay patient and slowly accumulate while sentiment stays weak.
