RBN is an independent in-game token (utility token). RBN is not a 'Hive Engine' token. Ideally, SMTs are implemented on the Hive blockchain asap, so that we can create RBN on the basis of a decentralized blockchain. We have a number of tasks to complete before we take these steps. When the balancing is completed and we have left the beta phase, we will focus on these steps.
But you can already transfer RBN and thus trade RBN. This is not a problem for us at all.
