Bitcoin is attempting to breach the $90,000 mark but is facing resistance. On the BTC/USDT 1-hour chart, a cluster of sell orders is causing the price to pull back slightly. Another resistance point is noted at $91,150. Bullish traders aim to surpass $90,000 to trigger the liquidation of short positions up to $93,000. A spike in spot trading volumes, especially on Coinbase where Bitcoin often trades at a premium, supports this upward push. As always, trading involves risks, and thorough research is advised before making investment decisions.
