The cryptocurrency market experienced a downturn as the total market capitalization fell to $2.91 trillion on December 18, marking a 2.4% decrease from the previous day. Major cryptocurrencies like Ethereum, Ripple, and Solana reached multi-month lows, with Solana notably dropping to $123, testing its March 2024 support levels. In contrast, Bitcoin maintained stability, trading near $87,000 and approaching the $90,000 resistance level. Despite the broader market volatility, Bitcoin's value has been supported by reduced selling from long-term holders and increased institutional demand, which has surpassed mining output since November 2024, according to K33 Research.
