Hello Fagreewraws, welcome on VR.
First of all I better move the discussion over to the english section; second, I'd like to ask you to introduce yourself to give us all a better picture of who we're talking to.
As for your question, it is difficult to say, I would say as a rule of thumb don't end your auction early, let it spend it's course naturally; chances are the buyer will offer less than you can actually fetch. Also, there is a chance it is a scam, it is not unheard of.
Regards
