Best thing to do is an auction. But surely you should be able to get the similar price in BTC that you bought for..
Any suggestions of where can I auction them ?
Thanks for all your answers!
Right here on this forum in this section

Plenty of auctions going on right now that you can check and show how different people run their auctions.
For the most part they are generally the same rules, etc.. but everyone has their own twist, etc
