Why dont you show us the full details so we wont doubt about this. Most of this thread.gets a lot of red trust. So if i were you, dont do something stupid coz you will earn it. Your offer also is very doubtful. How can you do that? Is it gambling investment?
Just show us the full details. Thats all.
If he/she got some real idea, then you would have placed the proposal in public, but it looks like they are trying their chances to get few people money to a scam. There is not such thing which can earn 50% profit in 30 days unless people use it in gambling or very high risk investments so don't send any money to these people.
