One day is not the same on the coming day. We are inside crypto life so prices is not always in decreasing moment it will increase someday on its perfect time. 900$ is not the price for ethereum if we get its potential in the realistic view. For me before it will end the year 2018 it will increase again.
I also think the price of ETH will recover more. Though there are many scan projects are selling their ETH raised from investors, the low price will not last too long. Maybe the May will be higher.
