I like your enthusiasm, but there is no way that is actually an AM account. There are entirely too many transactions 24/7... This is most likely an exchange wallet. The transactions that are coming from AM sales addresses are simply AM exchanging btc for fiat.
I'm pretty confident it is, look at the dates the tx start look at the amounts around those dates, if it was an exchange it would b e flooded with waaaay more transactions some days there was even any movement of btc
At the beginning there was only big sums then kinda dies for a little (chip sales)it picks back up when tubes come out kinda dies again, then most recently when the prisma came out that's when it became really active, check out chart below

Ill go back and make a post that's put together better so it doesn't look like I'm grasping as straws
