I haven't been in Leaptrade that long. I recently joined last year 2018. This is for those who just joined Leaptrade.
I sold two games and it was really fast! One of the things you have to know is that the credits you receive from selling is that it can't be withdrawn. You have to use those credits to request another game. The only thing that I'm having trouble is that I requested a few games and its taking time. So now I have credits that can't be used until someone accepts it.
