The main problems of hadronic Bc production were discussed. It was shown that: 1) There are indications that the theoretical predictions underestimate the experimental values. 2) The missing of photon from Bc* -> Bc + gamma shifts peaks by ~65 MeV and broadens them by 10-20 MeV. The photon is too soft to be detected. 3) The best chance to be found first on the Bc + gamma spectrum belongs to 2P excitations. 4) Bc(2S)-> Bc(Bc*)+ pi+ pi- mode is seen at LHCb, it should be seen at LHCb. 5) NLO cross section estimations for Bc production are needed. 6) Reliable predictions for one of the branching are needed.
