Sadly, I'm in the US, thus unable to access their trading platform.

Arbitao security bot aka AI has successfully locked me out from joining the site because I'm in the US.
I've never in my life have seen such security in all my years on the Net.
I mean, the Arbitao site asked me if I'm a US citizen and I clicked yes, whereupon no joy.

Them fuckers are good!
WAIT !!!
I have an idea. What if I ... BRB.
Okay, I'm in by tricking the security bot/AI, clinking the box declaring that I'm not a US citizens. Believe me when I say my balls were sweating for the two whole seconds the site took to approve my application. In essence, maybe I hacked their site.

Anyway, now that I'm in like Flint, I took a look-see at their live trades. At first glance, I was taken aback in seeing the millions I could be making via their platform until, that is, I realized within 1.5 seconds exactly what I was viewing - RSS feeds of select trades via APIs of exchanges (hence their phrase "working with these exchanges"). A simply script is employed to display the arb percentages is all. NONE of those trades are/were/or ever will be executed by us mere mortals.
