We calculate the ground-state energy of the $bb \\bar b \\bar b$ bound state, where $b$ stands for the bottom quark, in a nonrelativistic effective field theory framework with one-gluon-exchange (OGE) color Coulomb interaction, and in a relativized diquark model characterized by OGE plus a confining potential. Our analysis advocates the existence of uni-flavor heavy four-quark bound states. The ground state $bb\\bar b\\bar b$ tetraquark mass is predicted to be $(18.72\\pm0.02)$~GeV.
