If the money you use needs to be spent in other places and it is required to be used with the mark then, yes. But if the exchange is without the mark of the beast then it's merit will be based on the items bought or sold. This time of the beast will also be after the rapture so believers in Jesus Christ will not be involved as they will have already been taken to be with Jesus Christ. This tells me that the rapture is coming very soon and that it would be wise for men to have even a mustard's sized belief and faith in the blood shed and resurrection of Jesus Christ. Also to mention that many men, women and children of the past from time of Jesus Christ to now have been killed for their belief in Jesus Christ. Your sovereign individual myth will not save you! The apostasy of the devil's counterfeit will be as another fiat falseness.
