>Satan and demons will be bound at the end of the 7 yr Tribulation.
Correct and after the millennium they will be tossed into the lake of fire.
[Rev 20:7-10 KJV] 7 And when the thousand years are expired, Satan shall be loosed out of his prison, 8 And shall go out to deceive the nations which are in the four quarters of the earth, Gog and Magog, to gather them together to battle: the number of whom [is] as the sand of the sea. 9 And they went up on the breadth of the earth, and compassed the camp of the saints about, and the beloved city: and fire came down from God out of heaven, and devoured them. 10 And the devil that deceived them was cast into the lake of fire and brimstone, where the beast and the false prophet [are], and shall be tormented day and night for ever and ever.
