thanks, I'm such an idiot, I just didn't understand what gas was. There's no way to get that back is there?

Hey guys, this is gonna make me look really stupid. I'm a bit of a crypto noob but decided to try and buy some kin today on ether delta, which I managed. It was complicated as hell and I tried to do loads of small things several times, each time changing the gas amount. I thought the gas amount was like a limit and so I set it super high to try and make my deposits and trades go through. I also did this through my ledger. I go into my ledger tonight, 4 hours later to look at my balances and I'm 5 eth down.

heres the transaction record https://etherscan.io/tx/0x89bc94ac2a7fe881fac758dbf0a40604998bc10bbb68068eb8d53873b9d820ad

Did I get hacked or did I somehow manage to throw away 5 eth by setting high gas prices and fiddling with the totally unfriendly interface.

Thanks!
