BBR doesn't have a "sugar daddy" effect not network effect. It will get it's backing in soonish time.

Zoidberg is not a one man team. He is also widely suspected to have written major portions of the original CN coin. I also suspect he is thankful_for_today (could be wrong on this one), so he is never going to focus his energy on XMR. Instead he and his small team are working on just improving BBR all around. His work in not closed source, contributors are going to come to BBR just like they came to XMR.

Cheap current valuation is nothing to worry about. Accumulate and speculate.

XMR was on a terrific track until it started getting hastily shoved down everyone's throats by pumpers and a certain exchange. In due time BBR will rightly surface over the XMR drawbacks.
