Bitcoin and Ethereum user balances on centralized exchanges have fallen sharply as investors wait for higher prices in a bull market, with the value of Bitcoin falling to less than 2.30 million, or about $158 billion, while the value of Ethereum has fallen to less than 16 million, or less than $58 billion, according to Glassnode data. The user balances of the two major cryptocurrencies have fallen to their lowest point in four years, a move that analysts interpreted as a bullish signal for the future.
