Abstract
We outline the most important results regarding the stability of doubly heavy tetraquarks with an adequate treatment of the four-body dynamics. We consider both color-mixing and spin-dependent effects. Our results are straightforwardly applied to the case of all-heavy tetraquarks . We conclude that the stability is favored in the limit pointing to the stability of the state and the instability of all-heavy tetraquarks.
