I think you can sell a little portion of it now at least the price is not that bad yet. The next month is somehow promising and we really don't know of the trend. Selling it on the time you need it may also be profitable or you can acquire losses. However, at least you have some portion sold now, the difference will not be that bad I guess.
Selling portion by portion when price increases depending on the chart is a good choice for OP. He needs to be active seeing the market so he can take the price that it will increase and sell, he can also ship into alt which is increasing. However it will all depends on the market performance.
