I wouldn't compare BRN to BUD as BRN is highly speculative at this point until the technology is proven and scalable so when and if it does, it will explode but before that, it's high risk especially before the relisting as there are risk that relisting might not go ahead.
BUD is a whole different animal with a "not so farfetched" technology, immense growth industry to be in, amazing credentials to both management and board of advisers.
PS: I do hold BRN as well, waiting for milestone 2 patiently
