It was actually being speculated that BTS might disband in the year 2020. This was said due to the fact that Jin, the oldest among them, would be registering with the military. However, the band has extended their contract with Big Hit Entertainment till 2026. This really makes it very uncertain that the BTS group would really disband. However, a report also submitted that if Jim actually signed up with the military, he can be discharged for some important reasons as if he has a performance with his bad.
Also, if others find their way, they can actually still continue with both their job and the band. In addition, there was speculation that around the year 2020, the group might not be financially buoyant enough again to sponsor themselves. Despite all, I am more convinced that the group will not disband in the year 2020. They will certainly want to cover the contract they have signed with Big Hit Entertainment till 2026.
