The purchase on Friday at $.25 may have been the result of what is sometimes called a "fat finger trade" wherein the person placing the order entered the wrong number(s) for either the price of the buy/sell order or the trade size. With this trade, $.25 could have been entered instead of $.025 as the buy price.
Such trades can be an attempt at price or chart manipulation (especially following a R/S), but IMO this looks more like an order entry error.
