I have recieved 50% of the full 0.1btc lost in this transacion from Atomic Wallet today, here is their reply:
" Thank you for your reply.

If you would have owned your DOGE keys, there would be a chance for the recovery. However, in this case, there is not.

We would like to offer you 50% compensation – 0.05 BTC. We admit, that there was a failure in the wallet that has not prevented you from making a mistake. However, we want to note that it is on the user's side to make sure you use a correct address and double-check everything before sending.

We hope this resolution is acceptable for you, please provide your BTC address."

So they actually admitted it was their failure in the wallet, and they returned me that 50%. The other 50% which is a little over 0.05 BTC is lost, ffs that's still 400 usd... I guess I can accept that. Have contacted the site on which the dogecoin wallet is, so maybe i still get the private keys to that doge wallet and recover the rest. Thank you all for your support. They do admit the failure though...
