In my view, the premise of the question is narrow or flawed. The question failed to share the interests or area of expertise of the 1k holder in this vast carding business. This might have hampered sincere challenging, ambitious or adventurous advices. But, If I were you, I would have rather framed the question to be "what would you (as a carder) do with 1k in your LR account that would double,triple or maximize the return on investment in a specified time"?. Please post suggestions.
