not really. nor does the glitter and the photo really help. problem is they will infiltrate vendor ,or maybe your ISP or he device u take picture with, replace photo.

u would need something that you do not have to check online which is physically given to you by a known person. who do you really know at the vendor? no one. there isnt this person.

that being said,.so it comes back to trusting someone if you are dealing with digital things, somewhere down the line. That trust can be attacked, so u need to ne aware of it and if anything dont put all your eggs in the same basket.

Say you have 10 million$. you would want to split it up in chunks the size of your acceptable loss * the chances of such loss occurring, so that whenever you lose something, its within accepted risk parameters :')
