actually that's not really accurate, or just plain wrong. or overly simplistic view of the world.
since the production of the other coins is dependent on "farming" and so on. So it is like claiming that the BTC market cap is 10B even though only 55% or whatever of the total coin have been mined.
when those other coins come online it means that they are being created via the service mechanisms that maidsafe uses and therefor should provide some multiple of the book value of those services or perhaps a multiple of the revenue/profit generated by "farming" or some combination thereof including the perceived future value of those services. just like the very last bitcoin mined should be worth many multiples of the first ever bitcoin mined...
what it is saying is that if they had that system in place now they think that is is valued at 8 M as an "economy"
more sophisticated people than many of the people on this msg board have figured it out already.
The difference is with Bitcoin there was no pre-mining or IPO. So the Bitcoin initial valuation was merely the value that people were willing to pay for the coins or a market CAP of fractions of a penny. Maidsafe is starting with a market CAP of ~10million initially with a starting valuation ~126million.
As an investor the risk appears to be a hardfork of the code to be added as a future bitcoin sidechain without an IPO and without a 15 % tax on farming.
