Yep, I'm just being very conservative. I think a near term price of multiple thousands would require some significant improvements in usability and privacy, however. Beyond just the space savings of bullet proofs, Monero transactions need a larger anonymity set. I don't think that the current ringsizes are sufficient for truly inscrutable privacy.
I haven't heard much about RuffCT/RingCT2.0, or whatever it's called now. If I remember correctly, using the entire blockchain as an anonymity set was mentioned at one point. Any news in this area?
That was put aside because RuffCT would need trusted setup. Monero Research Lab is still looking at progress of it, but as it is right now it cant be added to Monero.
RuffCT and RingCT2.0 are two different things afaik CT2.0 is the one with the trusted setup.
