Max coins lost?

Does anybody know the max amount of coins you can lose by getting attacked? In battle islands it was about 100,000. I am scared to keep a lot in my inventory until I know.

definitely not a 100k cap. attacked someone in industrial age and could take up to 925k. but in my experience they only take 15% of you inventory

Ok thanks. 15% isn't bad at all. Time to start saving coins.

Just an update. Cannot get past the 400,000 mark. Get attacked and lose about 200,000 coins. Note that the attackers take half my money but always get 0 stars for attacking. Thats right. I get a defensive victory but still lose half my coins. BS

seems like they can take 100% of coins that are not collected from industry buildings but only a %age of coins that are in vaults.
