The address you posted has received approximately $200 worth of coin, and has spammed over 5,000 transactions onto the blockchain, but you are wanting to buy $40 million worth of coin?
My unsolicited advice is to find an OCT broker if you really want to buy that much coin. Or you can create your own OTC business.
It would frankly be insane to even consider trading with you.
Yes, Satoshi will forgive me for blockchain spam, but if I send these transactions, it means there is some meaning for which I pay. If I posted here the mention of this address and signed the message, then this also has some meaning. If this meaning is not obvious to you, it does not mean that it does not exist.
I hope that further comments will be on the case.
