Glassnode: Bitcoin retests $81000 'ETF cost benchmark', if it effectively falls below or dips into the $70000 range Glassnode has announced that Bitcoin is once again testing the ETF holding cost benchmark of approximately $81000. This price level had previously limited Bitcoin's rebound in May, but the market subsequently fell sharply. After briefly falling below this level last week, the price quickly recovered. Glassnode points out that if BTC effectively closes below this level, the price may further drop to the $70000 range.
