Thanks for the vouch copy. The ebook is good and it has a useful method to earn 0.12 BTC. However, the formatting and language needs improvement. Also, if you could have a step-by-step method instead, it would be easier to read. Adding more screenshot also would help as the price you have asked is $10. The ebook should atleast have 4-5 pages and you can get them by adding more screenshots if possible.
Dint know the method is already leaks but anyways.
That method is mine, and it has been leaked publicly. He just rephrased it. I bet he used google translate to translate to indian then back to english.
