This is what I think has happened:
If you had 0.409618 BTC.

You send it from your wallet 1En4edfmbtbstMXcwgdtR4AxJBgXQDonCY (0.488854 btc balance).
You sent 0.409618 BTC to 16VQ8J5CjP7rMjhrHUMy6eSUEiYQVXnX9k [was this your coinjar wallet?]

That wallet had 97 transaction. Total received 38 btc and with final balance 0.015 btc. It looks like a coinjar wallet to me.

If it was a thief, they would have sent all your 0.409618 BTC to their wallet in 1 transaction.
Instead, your wallet sent your btc out many times and incoming was many times too.

So it looks to me that coinjar is actually using your btc for their purpose ... so your btc balance in coinjar should be the same as before (0.409618).

Go to your coinjar wallet - Click on Managed Wallet on top menu and go to Home and see your last transaction - if it was sent and Processed in their system.
