On December 20, 2023, the ETH/BTC ratio reached an important support, namely 0.049. As it touched the coins in the ETH ecosystem rose sharply, ARB, OP and others. My opinion is that we are at the beginning of the ETH Etf narrative that will be doubled by an upgrade in the Eth chain, namely Cancun. Targets on the ETH/BTC ratio would be 0.058, 0.064.
