Could explain the current selling pressure. Some longs could be selling in order to take that money to get better terms directly with the company. And/or PT could be selling a few to scrounge up the last few K to pay off the loan at end of week.
The company's 10-Q filed with the SEC on 2/17/2018 states;
On November 14, 2017, the Company issued a Convertible Promissory Note (“Note”) to JMJ Financial (“Holder”), for a principal sum of $166,667 plus one-time 10% interest charge of $16,667 which matures on May 14, 2018 for $150,000 in cash. The Company may repay the Note and interest any time in cash before the maturity date without a prepayment penalty. If the Company defaults on repayment, this Note together with any unpaid accrued interest is convertible into shares of common stock at the Holder’s option at a variable conversion price calculated as lesser of (a) $0.0375 or (b) 50% (40% if the conversion shares are not deliverable by DWAC) of the lowest trade occurring during the 25 consecutive trading days immediately preceding the conversion date.
