If the wallet is still untouched and the coins are there without being moved, you may had the chance to get back your coins if you'd have stored your privkey somewhere else as a backup instead of just relying on that paper thing.

Maybe you forgot where did you leave your wallet? Why not have a brief checklist to check it almost everywhere on that list before you declare it as "stolen"? Stories of paper generation issues are also being screamed out nowadays that BTC is gaining traction, the only thing I'd advise is to generate a paper wallet offline (cut any connections to the internet while generating it/them) even on the most trusted sites, so at least you'd be safe just in case the website goes the wrong way! Just a question:

Why didn't you create a paper wallet by getting a wallet (maybe Electrum, maybe Bitcoin core), using an address out of it, storing your coins there and writing it down directly on a paper? It'd have definitely saved you from the hustle and your 1 BTC too.
