One each
Every share is identical, and every person can hold one. Nobody can buy more, so nobody can buy their way above anyone else.
Not for sale
Your share can’t be sold, given away, pledged or inherited. No one can buy you out when times are hard, and no lender can ever take it.
If you no longer want it, you can surrender it at any time — and claim again later.
No perks, no referrals
There are no rewards for signing anyone up, and no perks for members. Your share is the same whether you tell no one or everyone.
