I've seen a number of scams revolving around forex/sports arbitrage, and it would warm my heart if you could appropriate their marketing techniques for a genuine product. There was one in particular which I read all the copy for in sickly fascination. I couldn't find it again, but if I do I will post it to this thread.<p>They often have a ticker of out-of-date arbitrage opportunities, to demonstrate their capabilities. Your trial is superior to this in one way, and inferior in another (which is key.) You offer real moneymaking opportunities, proving the value. But potential clients, as you're well aware, do not yet trust you. And running your code requires trust. I think you should take a leaf from the con men's book, and show out-of-date opportunities on your site.<p>The scammers give an explanation of what arbitrage is, and what "separates" their system from a get-rich-quick scheme. They invoke images of fast cars and big houses. They are, of course, exaggerating to prey on the naive and desperate, but the principle holds for a real product. The wikipedia page you link to is sterile. If it were me, I'd write an explanation which dealt directly with gigahashes, and which sought to excite your customers and inspire them to imagine their pile of BTC growing every six seconds.<p>These next thoughts are more my own. If your software is any good, people are going to reverse engineer it; why not post the mathematics behind your system on your site? If people can see the basis behind your program, they've a reason to trust it. Even if they don't understand the principles, they'll be reassured to see that there are indeed principles. I'd put up all the personal details you're comfortable sharing. If people can read a bio blurb and see your face, and feel you've made yourself vulnerable, they're much more apt to make themselves vulnerable to you. (Of course, if you put up too much information the vulnerability ceases to be metaphorical.)<p>Additionally, while I understand you can't compromise your competitive advantage, I'm curious to learn more about your system. Is six seconds an arbitrary number, or did you arrive there empirically? Are you running the tool yourself? How much have you made? What would be the impact if many people started running your tool, and (if their clocks sync up) take advantage of the same opportunities? Would that degrade its utility?
