And how can you guarantee that?
I can't guarantee that because I have no way to do that but I've been contacting groups who've shown interest in doing business with me and can refer thousands of potential buyers in exchange for a 50% commission, as stated in the website.
If you are so sure I don't see why you can't pony up some collateral.
I don't give any collateral because I don't have any to give.
Not to mention what happens if you book earns squat - how are you going to be able to pay back the loan if at all?
I've been working in this project for months and now it's ready to be launched. I'm confident it can make far more than enough to pay the initial invesment, the return on investment and still make profit. The book worths the price being asked (0.01 BTC each copy) and the quality is very good, so all it needs to sell is left to marketing. Since every referral partner will receive 50% comission then to cover the initial 1 BTC investment it's necessary to sell 200 copies, and 600 copies to cover the proposed ROI. I believe this is achievable.
Now what if for whatever reason the book doesn't sell enough to break even? Well in this case then neither of us gets paid, that's it, especially me, because the investor at least will automatically receive whatever the book makes up to 3 BTC.
I understand your concern about getting scammed, but let's make something clear: I'm not looking for a loan but for a business partner willing to invest 1 BTC. As with any investment there is always a risk, this one is no different. Now if you want to make 3 BTC without the risk of losing a single satoshi then there is an opportunity for you: you adapt the code to suit the website's needs and I pay you 3 BTC for that in the model described previously. Of course it requires you to know PHP, Python and MySQL, but at least it's risk free.
