We report the results of \textit{ab initio} simulations of the electronic properties of a chain of C60 molecules encapsulated in a boron nitride nanotube - so called BN-nanopeapod. It is demonstrated that this structure can be effectively doped by depositing potassium atoms on the external wall of the BN-nanotube. The resulting material becomes a true metallic one-dimensional crystal, where the conduction states are formed solely by the fullerene chain. At the doping rate of one K atom per C60 molecule, the system shows the density of states at the Fermi level considerably higher than in any of the fullerene crystals presently made. This makes the doped BN-peapod structure an interesting candidate to study a possible superconducting state.
