Before investing anywhere you should take a close look at the company & the team. For me they look good especially because the team is very good. Mahoney made a similar arbitrage software for T3 Trading & Splunk back in 2005 (or 2006, not sure) so I think those guys know what theyre doing. But you should check it yourself .
I'm sorry, who?
Couldn't find his name on Google, besides there are no linked-in profile provided.
It's very common to find Linked-In profile on website like this, this to ensure that the team written on the website are real and not a bogus team.
This could be his linked in profile -
https://www.linkedin.com/in/tony-mahoney-2a9863111/deBut in my opinion, this Tony Mahoney is a fake person. I can't find any authentic source that he is actually real. He even don't have any picture except that black photo from the profitcoin website.
Also, if you will take a look on that single photo. There is something unusual between the nose and the face.
It have different shade of light, photoshopped? Probably the face and mouth was taken from a person, then pasted on another's face. (sorry, Tony

)
