Usually prices to sell are over, these prices are quite low and if you think you can get a good position with low selling then you should sell, i choose to wait.
As a trader i dont sell my coin when the price of it is low, i always wait a perpect time or perpect oppurtunity until the value of my coin will increase again and then i will sell it, i think you better wait until the market will be green again so you can sell your coin with higher price.
