Play2earn, could have happened, if I wouldn´t have minted two avatars at 100 SAND each.

As you can see the best offer, after the event has closed, is about 36 SAND each.
Finishing the event paid 98 SAND, so if I would have had only one avatar the reward would be at ~134 SAND which would be 34%. Sounds nicer than it is in fiat money, even with the actual pump the gain would be about 10,66€.
But hey, 10€ for playing and finishing a game in under one hour. Had fun AND got paid. ...if I wouldn´t have bought two avatars :-/

Lesson learned, keep the investment as a minimum and sell the avatar as soon as you finished the event and it is still open for others. (Best offer then was 90 SAND)
