Nobody is going to buy your guide unless a trusted member of the community has seen it and verified its content. A lot of information is available for free and if you have a better method on making money it needs to be checked.

When your e-book is ready, post some info on its content, and offer a free copy to a trusted user who would be interested in verifying it, and vouching for you if it's legit.

I'm not sure if arbitrage really has a specific guide or you just have a list of exchanges that have a % chance of making a profit and want to sell the list. In this forum, many "pro" guides are distributed free of charge.

If I want to be your first buyer, then what I need to know is a valid proof of your trading history and income, the exchange you are trading on. How often you make profits may be a benchmark price for your guide.
