From USD2000 dropped down to USD1400 for only 2 days?
Anyone knows what is happened?

if you can answer that Bitcoin reason of dumping , from 58,000 down to 43,000$ then maybe i can answer yours?
Market is falling down so expect the value of each coins as they are most all dependent in what Bitcoin movement is.
But ETH is a coin that has no strong position , not like other coins that has been pumping too much while now ETH is not that good and always delay in running good.
Maybe in a week or 2? we can see some growth again but don't expect too much.
