Take that as an opportunity to buy more ETH, we have to learn to use the fall in the right way, you could reduce your loss by this step too and you will be less nervous at what point will the price stop.
I am sure that Ethereum will not fall below $ 250, because at this level it has a very strong support from investors.
I hope always supporters have big support ethereum to pump . 250 dollars price of the ether and I hope it will not decrease anymore because that is not good.
Less nervous now than the people who buy a loy of ethereum when price is thousand of dollars and you can make more profit on that .
