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.
This is because most of the altcoins are Ethereum platform base and relatively there are many investors of ETH since it is next to bitcoin and the people are thinking also that ETH may overtake bitcoin in terms of marketcap volume. Now they are withdrawing and getting back to the original and dominant crypto which is the bitcoin. So what happen to ETH? THe market price for ETH has huge fall down and its platform the ERC20 coins are being affected also.
