I know this guy Amit Bharadwaj, met him once in India. He even cant speak English properly and now is selling 3 books which he claims he has written. The real story is that he took money from investors in his venture called gainbitcoin and promised to pay 10% of invested amount for 18 months in BTC. He collected huge amount of money and invested around 120 million INR in gold mining where he failed miserably and now is unable to pay to its investors. The gold mine venture gulped him down and so the investors.
