Bitcoin is currently testing a significant resistance level at $89,000, according to analyst @alicharts. A successful breakout above this level could propel the cryptocurrency's price to a range between $91,000 and $93,500. However, if Bitcoin fails to surpass this resistance, it may experience a pullback to $84,600. The potential upward movement in Bitcoin's price could also positively impact select altcoins, which may benefit from the bullish momentum.
