I don't understand if it was dump why the same party buying back. SP is going down because the buy orders disappearing. But buying back resists SP getting down.
Look at the intra-day chart, the dumping of 4m at the around 13:00 PM pushes the SP to $0.12 and another 4m half an hour later makes SP stays at $0.12 and below.
I predict SP will be dumped to below 0.10 or more before it turns back.
