If you're in the US, it's too late to sell for tax loss purposes for 2016 tax year. However, you can apply it to 2017 a year from now.
The math is so simple it's a no brainer. If you don't want to miss out on a potential positive gain, buy a million shares at .0001, and then sell the old shares. You'll have 85k that you can use to offset capital gains elsewhere (if you have any) or deduct from your taxable income at the rate of $3,000/year. You can carry it forward until it goes away if you live long enough.
If you don't want to risk the 100 bucks, just sell....
