1. last bidder will get 50 LTC on the price of last bid but the second last parson to bid also have to pay the bid price made by him.
why 2nd to the last bidder should also pay for the item he will not recieve? what if the 2nd to the last bidder wont pay?
3. All bids will be discarded if we are getting more than 15% loss.
then this is most likely a auction with nowhere to go if you didnt get enough bids?
Twist - second last bidder also have to pay for that this way the winner have to pay less than the actual price and if the second last bidder disagree to pay he will get a negative feedback and the auction is cancelled.
Yes i found a block though solo mining and it cost me 0.3 BTC so i can't afford to give it to you below that.
