I think that, from my experience, it is best to play games, T-time, Trivia, etc., accumulate a lot of TC, which will have a large number to be able to bidovati at auctions that carry double the MRP.
Also, one way is to charge your card the money and so you buy a product or a lot of TC, which will bring additional mrp when bead on the double auction ...
I hope that my answer helped at least a little
best regards and see you at the top!
