German hamster Mr. Goxx is running circles around the competition in the cryptocurrency arena.

The rodent started out with the euro equivalent of $390 on June 12 in his exchange account, which was set up by his anonymous owner. Three months later, the hamster has managed to grow his overall asset portfolio to $498. The increase puts Mr. Goxx ahead by nearly 30%, outperforming Bitcoin, the S&P 500, and even Warren Buffett’s company Berkshire Hathaway, according to Protos.
