Um, this sure looks like a mistake.

I finished in third place, for 15 Hive.

But instead of once, their server paid again, and again, and again…

Did the same thing happen with other players?

Edited to add:
Looks very much like a glitch. The Hive account@cryptobrewmaster wallet was emptied. Everyone who placed got paid 7 or 8 times until the wallet’s balance dropped below 1 Hive.
They’re going to want their funds back...
