I would almost bet you have a blown head gasket or a cracked head. White smoke at the exhaust, loosing coolant, moisture on the underside of the oil fill cap, and on the dip stick are all signs of a blown gasket. The fact that there is no coolant in the oil does not mean it does not have a blown gasket. To find out for sure remove all spark plugs, disconnect the coil wire, and then run a compression test on all cylinders. If you find one or more with low compression you have a blown gasket. Do not drive this car any longer until you get this repaired. Serious engine damage will occur if you continue to drive it.
