It seems to me that every project has a total amount of coins that is to small. There is 8 billion people on this planet. Each will possible have 10 000 dollars. Safe need to have enough safecoins so that each human on this planet can have 10 000 safecoins. If not at first then at least in the end. Anything less than that and the total amount of coins will be to small and thus becasue of this be not as usable and desirable to use for trade as it could be.
Safe should aim for safecoin being the most practical and desirable medium for trade and wealth-storage. And to that end the number of coins need to be around the amount of humans on earth times 10 000. A to small number will in itself hamper the coins usefulness for trading and as the everyday medium to make business. It would be very unfortunate to choose a total number of coins that is to small.
