Well another project a bit more elaborated then the usually doublers running it may let some people to double but others wont see a satoshi from it.Its more risky then any thing,and you main investment will return after two years.
Return in two years? May be in dreams... Never invest to any doubler or HYIP kind of bitcoin investment programs. They will swollow your money in one or two days after giving you some initial confidence. Better stay away from them always.
Now i see the mistake,anyway those kind of websites run not more then a month,usually as the deposits start to decrease its when the admin run away with the bitcoins,i should had said 2 days or 50 hours.Anyway this is just another scam that people will try to get more coins but in the end you may end without a pennie soo avoid it.
