OTCQB is described as "senior" in..a few places that I could Google, but Investopedia calls them "mid-tier". But thanks for clearing up that a reverse split is not required for a BZWR uplist if they choose OTCQB. I hope that BZWR keeps the goal realistic and gets listed on OTCQB as soon as possible. I think that the other exchanges will have to wait.
