Are fancalls or virtual fansigns the reason for increased album sales during pandemic?

Discuss

probably

because before fansign were only open to Korean fans because international fans couldn't do all the travel to go to a fansign, so they were buying in mass just for a collection purpose.

but now that fansign and fancall are open for every fans, it's true that it motivate international fans to buy much more to win their spot in one of them.

yes to the extend

Yes and they are more effective than photocards and different versions.
