I am the only one who lost money- either way.
This doesn't seem to be true to me. If person A was supposed to get a coin that was funded, but it was empty, that person has also lost money (not to mention reputation when re-selling it unknowingly as funded while it was unfunded).
When I peel the sticker I will show half of the key, redeem the bitcoin then paste the full private key to see if it matches with the ones I posted months ago. If that ok great if not then please let me know how I can change it.
You should check in with OP via PM (if possible) to see what they find acceptable first, then we can vouch in. Doing something that OP disagrees with won't help remedy the problem.
