Nice question dear member,
The answer is in what action you want to produce ?
If you want to win more TC's will be more helpful plaing games and try to win, one of most price's on all games EAGER.
Otherwise, if you need point's, action point's, bidding on auction will be very helpful, for collecting point's, win auction and receiving Member Reward Point's.
Don't forget that after every 50 bids you will receive an additional PSA in your downline.
