Look at the bitcoin the price is same when you compare it in February but altcoins are struggling too much and almost lost more than 60% of their value. I hope there is an expectation the prices of altcoin will recover once bitcoin price start increasing again.
It is their platform that has fall down that much which is the ETH. ERC20 coins are bleeding because of ETH market price fall down but still we should not worry because it could still bounce. We could not get good profit if market price is high already so there should be a good moment to kick off market price increase.
