Hey Dear There are Many Bitcoin Doublers Online, Are They Genuine or They Just Want to Loot our Bitcoins, If any Genuine Please Inform

Hey Guys

As I have come through these Doublers they ask to transfer some
Transaction fees and then they will Double our Bitcoins
Strange... I Mean Why can't they just deduct the Transaction fees and Transfer Balance

I really feel they are looting our Bitcoins
Has anyone Tried it
