Bitcoin has declined 16% year-to-date and is entering a historically weak period for returns, according to BIT analysis. Historically, June has yielded an average return of just +0.7% for Bitcoin, with summer months often marked by price consolidation. However, this year's atypical performance in May, which saw gains below historical averages, suggests a possible seasonal reversal. Upcoming catalysts, such as the launch of US-regulated crypto perpetual futures and Nasdaq-CME crypto index futures on June 8, could influence Bitcoin's trajectory. These developments may provide new buying support, potentially leading to a rebound despite ongoing seasonal pressures.
