The cryptocurrency is behaving as a high-beta asset, showing volatility similar to some blue-chip altcoins. Meanwhile, Ethereum (ETH) has fallen below $1,900 this week, with a critical support level identified near $1,600. The broader crypto market is witnessing a lack of institutional demand, with derivative basis points hitting multi-month lows and bearish sentiment increasing.
