If you are waiting for ethereum to dump to $30, you might as well wait forever because it won't happen. Ethereum has grown and developed to an extent to which it's market value should be in thousands not hundreds!. When market recovers, we will see the value that will be placed on ethereum!
Yes, I also tend to assume that the ethereum does not overcome the bar of 30 dollars. So far, it is unclear when there will be a growth of the market, therefore, in the hope that the price will fall below remains still the right decision.
