So, BANCOR is backed by ETH at 20% CRR, token A is backed by BANCOR at 50% CRR, which means that token A is backed by ETH at 10% CRR. In fact, now everybody can multiply money supply infinitely by issuing token B backed by token A, token C backed by token B, token D backed by token C etc... and ETH reserve ratio of each next token will go to zero exponentially. Is this the point of bancor protocol?
