Your last post is riddled with falsehood, so lets analyze them one-by-one:
Not 21 missions. The majority of these 21 missions are "incidental flybys" and failures. There is 1 successful sample collection from the Ryugu asteroid, which is thought to be comprised of nickel, iron, cobalt, water, nitrogen, hydrogen and ammonia (no gold).
"Hayabusa2 touched down briefly February 22, 2019 on the Ryugu asteroid, fired a bullet into the surface to puff up dust for collection and blasted back to its holding position, said officials from the Japan Aerospace Exploration Agency (JAXA)."
There is also 1 successful sample collection from the Itokawa asteroid, which also showed zero gold.
That's it. 2 sample returns, neither of which contained gold.
SGOLD has a proven automated solar powered technique for extracting and refining regolith using solar pumped laser light and is willing to sponsor missions with qualified vendors using this method, or a recovery and refining method they might develop.
Plans on papers. What guarantee do you have that anybody wants to do business with you?
SGOLD holders are ordering 20 years of gold production from automated space mines, recognising the risks. Delivery occurs every month after return of the first capsule. 0.1 troy ounce minimum deliverable quantity.
Again, dependent on too many contingencies to be a viable business model.
SGOLD contracts will be put together and project missions will be sponsored with qualified vendors using proven recovery techniques.
There are no "proven recovery techniques." So far the only thing that has been returned from an asteroid is dust samples.
SGOLD holders are customers that are making space mining happen.
No, the companies would perform their operations regardless of the funds raised here that you are throwing at them.
Each SGOLD is a contract to buy 1 milligram of gold per month from a space mine at 25% of the London Precious Metal Market price at time of delivery, for 240 months of production.
OK so like I said earlier, it would appear that an SGOLD token holder has to hold their token(s) for 240 months in order to fully capitalize on this. There are currently zero space mines. This might be the case for decades.
Each SGOLD costs 0.0041 eth and returns 1 milligram per month for 240 months, altogether worth 0.07292 eth by paying over 240 months a total of 0.01823 at time of delivery - netting a gain of 0.05469 eth for each 0.0041 eth SGOLD token. A substantial gain of 1,330% over the period.
Again, investors have to wait 20 years to capitalize on this, all while hoping the Ethereum platform isn't totally obsolete by then.
Each tile produced in space has an embedded RFID which is put in the blockchain at time of manufacture, and will likely sell at a premium to commodity gold, regardless of the prices here.
...
To get one tile each month requires the purchase of 3110 SGOLD at 12.75 eth and returns 240 monthly deliveries of 0.1 troy ounce of gold worth 0.9450 eth with the payment of 0.26325 eth. A total of 24 troy ounces from space worth 226.8 eth over the contract period at today's prices. Obviously both eth and gold are hedges against inflation or financial black swan events.
Again, this is all extremely speculative. As somebody who has analyzed probably over a hundred ICOs and token-based projects over the years I'd say the chances of this one being successful are far slimmer than almost all of them. And the bar is set pretty low.
Come back again in 10 years after the first gold containing sample may have been returned to earth.
