QS Energy Inc (QSEP)

[Myrka]

I have a question for the experts on this board.
Last Wednesday at the very last minutes before closing someone bought 100 shares for 38 cents. As a result, my portfolio showed an increase of nearly $100,000 just because of QSEP. You could say that last minute buy set off a sudden interest in QSEP. Probably many other investors were also alerted to this sudden increase in share price. Who would make such a buy and why?
Would it be a market maker?
In 2017, ZEROSUM you wrote:

CDEL is the robot on QSEP which is run by the market makers, and they constantly are throwing small buys and sells around. They jump ahead of the highest bid fractionally on the bid, and they go fractionally lower than the highest offer. Once they get filled on the bid or the offer, they then add shares to sell higher what they just bought, or buy lower what they just sold and they do this on every OTC stock all day long. They are constantly making money and taking advantage of the spread, and in OTC stocks the spread is wide. They make a lot of money just doing this while making a market for the stock.

I am curious and would like to understand how QSEP was manipulated and for what reason, what would be the objective of the 38 cents buy. Also, who would be doing this, the guy who bought 700,000 shares or the market makers?
