Hi,

I'm wondering if the OP or someone from Alitin Mint can help me. I am failing to see how this is much of an improvement from tamper proof holograms. I am not trying to cause drama, I simply am wondering if I am thinking about it wrong. I know since I also make physical cryptocoins this will likely look like an attack of some sort, but I am genuinely worried about the security of your product and the claims you are making of how they are more secure than original physical Bitcoins with tamper proof holograms. I have spent many hours lately doing different experiments on how to improve security on the original design of physical Bitcoins, but I don't see this as a very good solution.

I think you guys protected the coin from the obvious... radiation techniques due to the engraved private key, but it seems to me the only line of defense against retrieving the private keys of these coins is the hologram on the coin case. Which as we know can likely be removed showing no to little signs using acetone, just like the older coins that you claim are inferior to yours. That defeats the whole sales pitch here.. minus the very attractive coin artwork. The process a bad actor could take is:

1. Have a replica of the plastic coin case made in China for $1-5 each
2. Remove the coin from the packaging and retrieve the private key from the edges of the coin.
3. Remove the hologram from the original coin case using acetone showing no to little signs of intrusion.
4. Print new labels, QR code, whatever is inside the coin case and put them in the new replica case.
5. Place the coin back in the replica coin case you had made and seal it.
6. Place the hologram on the coin case back where it should be like nothing happened.

I know Alitin says "you can send a picture by email and find out if it is counterfeit or not". However, I have a hard time believing that they do not do this by checking a certain security feature they added to their hologram. This is something that can be easily implemented in the old design of physical cryptocoins.. just a coin and a hologram.

I am just failing to see how this is any better. It would require a little more work to tamper with than a normal physical cryptocoin, but it is still doable IMO. Even at today's prices there is likely enough incentive (cost versus reward) to do this... imagine when Bitcoin really goes to the moon. Please prove me wrong, the reason for my post here today is purely academic and I wish Alitin Mint all the best. I hope I can make it to the Texas Bitcoin Conference to talk about this with you guys face to face and in depth. I only live a couple hours away so I think I can come.. I just have to see if I can get off work.

Thanks
