Look im not trying to spread misinformation but if I recall correctly it reads must be advertised as HBAR or stamped HBAR.
How can you prove something was or was not advertised in some way. Take a screen shot of a website before you buy? Also where does it define who has the authority to determine what is or is not an HBAR and who has that authority to mark the barrel as such. Many companies simply put someone else’s product in a box with their name on it and just ship it out. Can they the distributor mark a barrel? If not why not?
