If your sponsor is blank on bitconnect, you can still change it. Even if you are registered.
Go on the left side under management tools and profile.
Then you can add or change your sponsor!
If you take me as your sponsor, I will give you back 7% on your next lending/investment/reinvestment! =) So you get a bonus on your next investment.
My sponsorname: balesch
Would love to welcome you in my team!
Thanks for reading!
