when i try to short doge on kraken i get: "Order type allowed only on positions"..is it normal or did i do soeomthing wrong?
You're probably trying to sell DOGE when you don't own it. Instead you want to stake BTC or EUR or USD to short DOGE. I'm not sure how it works since I have only used Kraken to exchange coins I own, but you could try use
https://trade.kraken.com instead of kraken.com, this platform is a bit more detailed and it might help you.
