I don't think any cryptonote coin will ever pass Monero, including BBR. But:
The idea that Monero is already too big to be overtaken is complete nonsense. I'm a big supporter of the project and hold much respect for the developers, but if a new technology comes along that is unquestionably superior, adoption will flood to the new tech.
Monero's fate will depend on it's ability to adapt or compete with emerging technologies, which will put it in an inferior position compared to its nimble adversaries. Some very bold decisions lie ahead for the core team.
I realize that things move fast in CryptoLand and from the near non stop
proliferation of "coins" it's clear to me that there is zero barrier to entry in this space ..
As long as the "next big thing" in crypto is open source wouldn't that imply that
Monero can adopt/modify as needed going forward ?? There's no real need to
constantly produce new "coins" for every great idea that comes along; we've got a
population of some 1500 alts now; surely that's enough to satisfy any "new" concept
worth trying out .. I've noticed that most recently launched coins are essentially "featureless"
with the dev/s promoting community participation in selecting from a 'menu' of potential
attributes for eventual inclusion .. I suspect that 'rehab crews' will relaunch failed/abandoned
coins with the latest desirable 'feature' set as a way to cheaply pump and dump for BTC or other coin ..
Triff ..
