It is not clear how the referral is calculated and displayed when?
Instant pay, when sum is great than minimal deposit. We can't sending little sums, because fee isn't zero. Be patient.
Let's see how this works, my investment 36968.99 DOGE
100000 DOGE ► 5% ► 5000 DOGE (minimal deposit for DOGE currency)
When sum deposit of all your referrals will more than 100000 DOGE then you get your commissions.
