Yes , maybe not you are the scammer, but the person with whom you were in contact.
This amounts are not traded here and for sure never ever anonymous.
Amounts like that are a 100% scam if offered here at bitcointalk.
Simply the amount of discount is not common with high amounts.
So it HAS TO BE a scam or a laundry of illegal money.
In both cases anyone entering that train, will loose.
Maybe you were not aware of that...
