Does "all upper grade sponsors" mean all three of the ones immediately above you, or does it mean all of them, up to the very top of a chain?
It means up to the very top of the tree.
Is this an accurate description of the payout system? Also, a couple of questions:
Yes, exactly!
Is there anyone who can find a better investment strategy? (i.e. faster and/or larger return) [/li][/list]
Beware that there will be two little changes in the next few days. The upgrade is almost ready so I can announce it already:
1) there will be no more chances to join without a referral. This is made to disincentivate people in making 0.x account with all the capital after, in order to help members receiving more rewards and a % of the referral (and sub-referrals) mining results.
2) Deposits will be kept separated inside the account. Now all deposits are joined in one single balance. Soon they will be kept separated inside an account, and it will be possible to see the completion % of each single deposit.
This will not change anything for current members, it will affect only new accounts, made after the update.
