Bitcoin tests its largest supply wall at $80,000, near ETF holders’ average price

On-chain and orderbook data show Bitcoin encountering its largest concentrated supply wall around $80,000. That cluster sits near the average acquisition price of Bitcoin held by ETF investors, creating a convergence of sell-side pressure and ETF breakeven. The $80k band therefore represents a key resistance that could cap near-term upside unless sustained buying — likely from continued ETF inflows — absorbs the overhang; failure to clear it would favor consolidation or a pullback, while a decisive break would likely trigger further upside as supply is consumed.
