Jungkook sold the equivalent of 10 million albums
I do not know how this figure is derived, but I think it is higher than what KPop's Greatest Freeloader sold in her entire LIFETIME.
Still, KPop's Greatest Freeloader had a world tour, although most of them were arena tours.
If KPop's Greatest Freeloader could do a world tour, Jungkook should be able to do a tour about two times what she had done!
It would be at least 1 million, probably significantly more.
Jungkook is at least two times, probably three times, more popular around the world than KPop's Greatest Freeloader.
By 2027, Jungkook's fans who do not really give a damn about other BTS members will probably have mostly left.
Given the way JK is speaking, 2027 will have concerts from Yoongi, Namjoon, Jimin and may or may not be Taehyung who might follow an acting career, and JK's individual concert will NOT be the priority.
The Korean system of honoring the elders, which made the 1,352 years FreeloaderW gain so much respect despite of all her long history of freeloading.
That means JK will have a world tour at the age of 31, the legal age when the Freeloader had her first (and probably the last, given her recent moves) world tour!
And the comparison is meaningless since the Freeloader did not particularly aimed for a global audience.
What global level singer does his first world tour 5 years after his breakthrough? I have never seen anything like it.
