The number of coins that will ultimately be in circulation at the peak of the DGB life-cycle is a lot of coins: true. This was not a mistake, but a prudent long-term observation. There are 6 Billion + human beings in the world. That figures to less than 4 DGB per person in the world, assuming the population doesn't grow -> which is a pipe dream. That means we are looking at even less than 4 DGB per person.
Many would argue that the world population has no relation to a crypto-currency. A fair argument; I think they are short-sighted. If we are talking about tomorrow, or this year, I think it is a very accurate argument. A true currency, however, doesn't exist today and tomorrow. It has to function 10, 100, 500 years from now.
You guys crack me up
"Many would argue that the world population has no relation to a crypto-currency" < FULL STOP.
Even the dollar amount available in the world has NO relation to the number of people on the planet.
"It has to function 10, 100, 500 years from now."
Really? 500 years? There is not one currency in existence that is 500 years old and you imagine that "digibyte", conjured up in a few weeks time (okay, months) will become the world currency?
Stop trying to make sense of something that doesn't make sense, please.
DGB was created to make a fast buck. (and yes everyone into crypto's is here to make money, except for the very VERY few).
