IconicExpert, you did not provide any proof or evidence for us in your text. I don't see any reason to believe some claims written on the internet without evidence. Furthermore I don't understand how they can dump 7.5M BC without changing the price when the pool only buys 100k back.
Please provide clear evidence for your claims. Until then I can only assume that this was a tactical move by you that in some way fits with your profit orientated plan.
