This is more like a direct referral system, not a pyramid.
your right, this isn't a good pyramid, cuz YOU as a sponsor will only get payed once per direct refferral,
all other fees are randomly payed to all members, no matter where they are located in the pyramid.
theres 42 accounts, right now 35 of 'em are activated,
what did u expect?
you already got 2 referrals, 1 of them isn't active though.
seems like you've already withdrawn those 0.5btc of the active one.
just be a bit more patient,
or at least come up with some suggestions on what to change.
