Socoban, I'm against you pointing fingers at Karma Team too quick without any evidences. That can be considered as FUD and can easily hurt the trust in this coin and it was very wrong coming from members like you. Take some more time and analyse more before pointing fingers at some one. Look at how this turned out to be in your own words,
Anyway, here is my opinion what happened. If there was really someone mining KARM few months ago with 95 MGH, than he definitely mined billions of KARM, since reward was huge those days. He was dumping it until KARM started to grow. Than he was waiting and dumping very slowly because he hoped for bigger profit. Since Kosmost announced 1. september as a day when KARM will skyrocket or dump, he decide to split his investment probably into half. He did not know what will be an announcement, so he dumped some of his coins to take sure profit before potential dump will occur and than he withdrew rest into his cold wallet, just 30 minutes left before end of august.
