Just a video about how bad some security holograms are

[Bullion-n-BTC]

wonder if that would harm a private key printed on regular paper. I use Revla paper (thanks to DaveF) and I am sure that would not be affected by this method. makes me question any second hand coin now...

I’m going to slap a laser jet printed QR code and an ink jet printed QR code under some holos and try this myself as I’m curious. I’ll send you a vid/pic of the QR codes and holos when I’m done and we shall see what they look like after and see if they are readable.

Try with the 99.5% if you can find it. In theory it will unstick the hologram the fastest while doing the most damage to the ink and paper.
If the QR survives that then you know that the lower concentrations would not harm it.
Obviously it would be best if we could test many types of paper & printers and inks and so on.
But that is just not going to happen.

Coming from the RC thread via your linking this  : figured I’d post this here .. not sure how many people spend time to go through my walls of text on Cold Stoage Coins (a scam coin I sniffed out pretty much right away..the signs for scams are often so similar, and I’ve just gotten pretty use to seeing them).

So this is likely an issue w other coins out there already and we just don’t know it.  There’s absolutely no such thing as a “fully secure” hologram at the end of the day, as you know.

I know I have said it before, but I still have very little trust that there are not some hologram makers out there that have not make a few 100 extra holograms so they could buy coins - peel them - reseal - resell and nobody would be any wiser till the shit hit the fan.

Look at the crap going on with the RC coins at the moment, what would we be thinking if a bunch of them were compromised and RC had made no mistakes, just the company he bought the holos from made a couple dozen extra and then had a bunch of straw buyers & sellers here move them around a bit and copy the private keys.....
