Seems to me that if they wanted to sell a bunch they could have contacted the company who would have arranged a cross for them. Looks to me like they're shorting. (protecting an already very short position)

They were on the ask at $1.80 and they kept beeing taken out. Why would they then ask for $1.76 now $1.73. Their objective is not to maximise the selling price but rather take the price down.

Looks like they're fighting a loosing battle. Right now buyers are just toying with them.
