Are you playing in Contract or Sandbox mode? What mods are you using?
If Contract, leave it there and wait for contracts to expand the station and send tourists (I recommend this mod https://forum.kerbalspaceprogram.com/index.php?/topic/175822-14-15-contract-pack-bases-and-stations-reborn/).
If Sandbox, turn it into an orbital fuel depot by attaching more fuel tanks.
