I found couple skullcoins in the map but not willing to import it because the transaction fee is higher than the skullcoin value. Correct me if I was wrong, 10k skullcoin worth 0.0001 BTC according to counterwallet but the transaction fee is 0.0001543 BTC.
that means the skullcoins token has already been claimed (actually all in game tokens have already been claimed)
the treasure tokens have been pre-funded so you can sweep them without any problem, when you see that it requires a transaction fee to swipe, it means it has already been swiped
