How does monero scale to billions?
Genuine question, because money tends to one medium of exchange.
Discussion
It doesn't right now.
But neither does Bitcoin or LN.
All these custodial solutions aren't really "scaling Bitcoin" either they're just dodging the question.
Monero has the advantage of adapting with new scalability tech when necessary because the community isn't allergic to upgrades. It already cut down transactions size by ~80% with bulletproofs alone.
Your question also rests on many assumptions...That everything has to scale immediately (even when there is no demand for it). That billions are going to ever use Bitcoin or Monero in the first place. That technology isn't always improving. That efficiency gains wont be made. These things will scale over time.
I agree Bitcoin doesn't scale in a non-custodial way at the moment. There is a risk that it never will. Giving up and starting alternate projects will mean that it never will.
If there is a risk that it never will scale non-custodially why shouldn't there be a plan B, C, and D available?
No one said anything about giving up. People will always start alternate projects. The birth of Bitcoin itself was an alternate project from ones before it.
I don't have a problem with developing alternatives, a free market is a good thing.
I see a lot of people give up on Bitcoin and relinquish their influence on it.
I can honestly understand why some give up or get pessimistic about Bitcoin. The ossificationists and NGU chart bois are rampant.
The only thing that seems somewhat promising is CTV and Drivechains. But the general community seems hostile or at least tepid about it thanks to the smear campaign by core & company.
