I see no problem. How about a referral program?
Yes, we do. The referral system (5,3,1)% works during the Token Sales period; after the end of Token Sales the referral program works only for personally invited people; the remuneration is accrued in BTT tokens; 0.05% from transactions of level 1 users, 0.03% from transactions of level 2 users and 0.02% from transactions of level 3 users.
