lol you can check transaction history ,who knows the address of your friend's 
yeahh why do you care about the address?

Geez lay off a little bit. He simply has a question about something that interested him, no need to rage.

A quick search on the address didn't bring anything up for me. It is trying to be claimed in this scam though: https://bt.irlbtc.com/view/977912.0 which you should NOT send btc too.

Would you ask who's money that is if you see a cash truck running on the road?    What you talking about is the same with this.
The money in the bank is private while the Bitcoin is an open book, that's the difference.

That's mine, I'd appreciate you stop snooping on my transactions. Thanks.

No. We cannot. Bitcoin addresses aren't bound to any personal data that the user have, so there is no way we can say who owns that address. Probably it is owned by an exchange or an online gambling site, but most of the latter often put tags that states that the address is indeed owned by a gambling site.

Lol
Are you envy?
I personally don't care about that except that Addy is scammer or DPR addy

That's the Idea behind Bitcoin . to keep the person behind it anonymous .
I don't think anyone could answer your question except the person himself .

Sorry, I should probably scale down my spending 
OP it is probably an exchange account or something.

Is $80,000 really such a massive amount to send and receive imo no it is not it is not peanuts by all means but could quite easily be just a normal trader sending his coins to the exchange to trade everyday because we do not leave them on exchanges for long do we? Well those who value their coin do not lol So not sure anyone is going to know unless it is their address
