I'd strongly advise you to make them unloaded, you can still engrave the firstbits or whatever and give them a denomination.
Reason for this is that a lot of members of the community have seen the harsh reality of loaded coins recently. We are now down to a handful of manufacturers that can be trusted (and who knows, more scandals might occur.)
So that would be my recommendation, I think you'd find it easier to deal with everything going that route too.
Thanks for your opinion. I will offer unfunded like I say but they will not have a private key in. Are the bad collectors mainly scammers or they were hacked? I dont really see how it can happen unless they scammed people.
If there isnt going to be a key i would say dont put a holo over it. DIY coins allow for a buyer to make his/her own keys if they so please to. As far as the coins, its a myriad of things. Expecting someone to place trust in your pricess/team with a full btc right now is sketchy at best. Nothing to do with you personally, just the current scene unfortunatelly
