I speculate that Supernet will have nothing to do with BBR's success or failure as a cryptocurrency.  While I was an early proponent of Supernet I have since become disillusioned with the project.  If it eventually succeeds and does what it promised many many months ago then great.  Currently I am not following nor do I care to follow the Supernet saga that is apparently still ongoing.  BBR did receive an initial pump when it was announced that it would be included in the Supernet platform but that has since evaporated just as the initial value of Supernet has declined significantly from it's initial pricing.

BBR suffers from the same problem that all cryptonote coins suffer from.  It's not bitcoin compatible and not easily incorporated into any of the current cryptocurrency payment processing schemes.  Until a legitimate payment processor devotes the time and resources necessary to accept cryptonote coins, nothing is going to change as far as adoption is concerned.
