That should have been the first warning sign that you encounter. No way in the world is a small site with a poorly designed UI going to be offering a minimum of 5% per day profit, realistically speaking. You can tell straightaway from that that it's either a ponzi, or a scam altogether that doesn't even try to be a ponzi.
Arbitrage in itself is a legitimate thing, but this bot is definitely fake. No one has ever heard of it, yet it offers such advanced levels of control and profitability? And why are they selling this, if they can make 5-30% per day themselves?
Seems like a total of 0.31 BTC was sent to the address that you provided, let's hope that nobody else falls for this.
