btw: XMR also dumped much at that moment...
20k daily inflation above 0.004 is hard to absorb for extended period of time even for whales and it's followers. I am sorry that they're bashing BBR along, they don't understand that competition breeds inovation and they act at their own peril.
Both XMR and BBR should be viewed as long-term, high risk .. you could call them investments or gambles, depending on your point of view. They're interesting because they *do* have some serious potential as the first real independent codebase from Bitcoin and with something fundamentally different to offer. But they're both very early projects with a lot of real work needed to be done before they'll start to have non-trivial use outside of speculation. I think it's silly at this point to worry about them competing with each other, when the real long-term is "cryptonote vs bitcoin derivatives that claim better anonymity."
Realistically, I think there's only one major risk associated with the ups and downs of either BBR or XMR's price -- the risk that the dev teams will get disheartened or not see enough upside in it to continue to devote work to it. I love BBR's 1% built in dev fee, because it delivers an ongoing revenue stream instead of providing an incentive to dump and run, but it does mean that the dev income is proportional to the price. Practically speaking, of course, dev donations in XMR probably have a similar relationship empirically.
While I don't think we've seen this problem much yet, Zoidberg & btc-mike, if you find yourselves unable to do as much as you want for the coin because of lack of funds, I'll happily donate some back in the hope that you can use it well to increase the value of my remaining holdings. I bet there are others who feel the same way.
