It's always tricky to advertise an investment opportunity outside. The LBI team is known here and have a certain level of reputation among hive/Leo users. You don't have that outside of the Leo ecosystem.
Many investment projects tend to use referral system to provide users inflow, but to tell you the truth, I would like to avoid that as it may become spammy and quite like ponzi schemes. Let's stay exclusive, let the people want to join in, not the other way around (at least on a communication level).
