I admit that BCH and BSV are far more profitable than Ethereum. but only for the beginning of the year until now. Many people get profits from both. Better you are patient. Don't sell the Ethereum that you have. If As you said, if the price of bitcoin does not up, ethereum prices do not up, then when bitcoin prices go high after halving, ethereum prices too will go high.
in terms of technology I think Ethereum Lah is superior, but for the price of Ethereum it hasn't been able to be good for 2 years, rest assured someday Ethereum can recover
Here, perhaps we should not compare technology when technology cannot be profitable or fully evaluate the potential of that coin in this market, what matters here is people's interest in that coin during this period. Right now, ethereum is considered to be more disadvantageous than BCH and BSV when the market demand does not belong to it, the pumps randomly appear in competitors, BCH and BSV are having a stronger recovery, eth can't be compared right now but remember, just for the moment, not forever.
