Though it seems a real fraud but in digital currency world getting 180 times the invest is not a surprise at all. With new crypto currencies emerging every now and then, one can bet on crypto currency and get filthy rich in no time!

I suggest you do some research on Bitcoin first, then go and buy some btc from Unocoin or btcxindia. But these services sell atleast 800-1300 rs higher than the current rate.
No one can say if btc value will be doubled in a year. You have to closely follow the btc market.  There are other crypto coins also emerging these days.
