Lost bitcoin on paper wallet
Only the ones with knowledge of the private key on that paper are able to send money from your address. If it's somebody else who also has your private key, it's weird that he/she didn't sent the entire balance.

Since it's impossible - let me repeat that, impossible - to send the funds without the private key, that leaves yourself as the only likely candidate who sent the 0,2 bitcoin.

Possibly you were performing another action like exchanging bitcoin for an altcoin using Shapeshift and you didn't (yet) correlate that event with the 0,2 transfer.
