Ether's supply on crypto exchanges has hit its lowest level since November 2015, sparking predictions of a potential price rally. According to Santiment, ETH balances on exchanges have dropped 16.4% since January, as investors move their holdings to cold storage, hinting at long-term confidence. This reduction could lead to a "supply shock," driving prices up if demand stays strong. However, Ether's recent performance has been shaky, down 26% over the past month. While some traders foresee a price surge, others remain cautious, noting bearish trends against Bitcoin.
