Does your friend only notice the transaction made?
It might be an exchange address but the last transaction was 2 years ago and its transactions are strange. All last transactions are outgoing seems paying its clients like a ponzi just like what other mentioned above and the forum profile linked is somewhat connected to the site mmmglobal?
Cryptasm was nice enough to create this post for me. I simply can't recall whether it was a wallet or exchange i sent to money to having made thousands of transaction in that time period.
I can say for sure though i did not invest in a ponzi scheme. I did invest in BitDice in 2016 but remember withdrawing my funds because i was too managing them in 2017.
