IMO POS on mobile devices ftw. Shit will get more efficient.
The most efficient thing is a fully centralised banking system.
Everyone using cryptocurrencies (at this stage of the game) should reallyyyyyy understand that "efficient" does not correlate with "secure", "trustless", "cryptographically secure", or "decentralised". It saddens me that proponents of Proof-of-Stake systems are incapable of understanding how much risk they're offloading on to users, the very same users that are trusting the system to look after so much of their wealth.
I think most of the world is still waiting for someone to actually audit the process of sdc>sdt and whether that transition is definitively needed for true zk anon.
I think most of the world has no idea what most of those words mean, and don't care about any of this;)
I like Monero too. I have held some but I did not see a direction for application IRL so I bailed. I think that, personally, what it boils down to for me is this; "where are things going?". I think SDC is on the right track and will fill an AIO gap that should push crazy volume. But that assumes it launches the marketplace and audit.
You sound like someone selling Network21 or Amway.
Bitcoin is doing just fine, in spite of it not having a "real world use" or "industrial use-case" or whatever the hipsters are blaming nowadays. Instead of looking for a
killer application to "push crazy volume" (a pump-and-dump term if I ever saw one), I think the focus should be on creating a truly fungible cryptocurrency that defends and aggressively protects user's rights and privacy.
