Do I have my math right?

5% of the wallet portion of the mycelium venture divided proportionally by the number of BTC raised in this round of funding.

If we accept the maximum 7,500 BTC are paid, then the stake of 1 BTC would be (mycelium wallet value * 0.05)/7500 or elsewise 1BTC =  (0.00000666667 * mycelium wallet value)

If we suppose the wallet is valued at $100mil (no real data here, just a number that has been discussed) then we could value 1BTC investment at $666.67

If the wallet grows to be valued at 1BN, then we go up to $6666.70.  Not much info on how they would grow the business 10x.  

Also, it would require them to sell the wallet to another investor in order to realize this profit.  In this case, I am concerned about the T&C that says they can require investors to sell back the token at ICO price.  Seems insane if I am reading those terms correctly.

Seems like very low upside for a very risky 'investment'.  As others have said, maybe treat this more like a donation to a good cause with a very small chance of ROI.

Also, some say that the token can be traded on the exchanges, but some say not.  Any clarity here?

Am I missing something?

Edit: for perspective, the Facebook purchase of Whatsapp was for $19.1bn.  Biggest deal in history for that kind of thing.  Getting sold off for 1bn is not exactly commonplace.
