It was open to anyone who actually did the work of mining not to mention the ongoing opportunity to mine.
It's still not fair. And the ongoing opportunity is not fair, you can only get a few millibits and lose money, while early adopters were each getting fat blocks every day.
While doing all that work and paying for electricity for BTC at a price of $0.05 and a chance for it to go to 0.
Coins mined today could still be worth lots tomorrow. At least we have a short at mining fresh coins. Not with POS.
even if we are talking about a biger timeframe here it seems some of you forgot that as soon the last btc is mined it turns into a kind of a pos system also,
where miners are rewarded just by transaction fees. nxt just jumps directly into this stage.
moreover, you can't be very sure that the btc distribution looks much better than nxt as soon it turns into this level.
just compare the real distribution numbers of both and don't argue that a mass of miners, who getting some pico-btc, are really changing this picture,
it's looking more than an ongoing wealth and mining concentration within btc than a real mass distribution.
it seems dynamic systems always tend to reach pareto, no matter what kind of initial parameters you choose.
added: using this analogy the interesting question is this.
assuming btc reaches this pos like level and also assuming the distribution follows pareto for btc and nxt at this stage.
which one of both will have the better, further mass distribution. btc, with a very high value, concentrated to 100 entities
or nxt with the same entities but much lower value?
as mentioned before, don't be toooo sure...
