I am designing a custom hologram for physical bitcoins, and I would like to make it multi-lingual.

What is the best word(s) to use to say something is a genuine item.

English words:
Authentic
Genuine
Original

This would be to signify that this item is not a fake.

Regarding brands, I mostly saw the word "original" was applied.

auténtico
genuino
original

Yep, you could use any of these three words.

I might just use original then, as it will take care of English and Spanish in one shot.

That works, but different "exotic" looking words would look nice too.

Space is limited. I think russian and chinese spelling will make it look exotic enough.
