I live in tier-3 city where I was recently introduced to Bitcoin by GainBitcoin Team. They asked me to invest 1 Bitcoin for mining contract. Return is 10% per month for upcoming next 18 months.
Can someone explain me the economics or return? It would be really helpful if you can quote me with difficulty level of mining. I think, return are dependent on it and price of Bitcoin. If not, then why are they thriving without any resistance in India, feeding on innocent souls?
