Largely from the same people who complain most loudly about inequality. You can lead the horse to water, but you can't make it drink...
Explain please how it would be possible to create something like bitcoin which does not in some way or other favor early adopters over later ones, I really can't see it so this is a genuine question. Not 'pre-mining' is roughly equal to simply not adopting it at all. I see it analogous to a founder not believing in their product to the point that they will not use it. Of course 'Satoshi' could have not pre-mined as much but who is to say whether those coins are even accessible today?
And anybody that joined in later than that already lost that early adopters advantage compared to those that joined earlier.
Which probably means that (wild hyperbolic assumption following) if you haven't done anything with it so far you'd look at me and my miserly number of coins as an 'early adopter' whereas I was - and still am - pretty skeptical about bitcoins long term viability.
I didn‘t say that there wouldn‘t be any favoring towards early adopters... a „better system“ will by definition always favor early adopters at least through efficiency gains accrued through the usage of the system over users who have not yet adopted. BUT bitcoin is crazy in terms of „value“ increase that is not related to any real gains in practice. People buy tokens because people invest money to find tokens because people buy tokens. And because everyone seems to be „making money“ from that things just continue... It‘s like with the rat who can control its own cocain supply...
So what I meant to say is - this specific system design is madness!
DLT in general is very interesting and I am playing around with some ideas regarding currency pegged tokens that increase in value if empirically verifiable achievments/improvements have been made. The goal is to create common-interest communities that are rewarded for realizing real-life impacts. So even people not participating profit. People who join in profit a little more. The goal is to have sustainable growth and predictable prices.
That's absolutely true but consider this: early adopters always have an advantage, in fact just being born earlier than someone else gives you an advantage. Family wealth, real estate ownership, rent seeking, tenure and so on are all linked because of this.
