We all know in South Korea, digital chart is not bringing a lot of money. I remember even "Gangnam Style" by PSY with 4,041,000 digital sales in 2012 alone only generated $38.000 from SK digital chart. While The cost for an MV alone is estimated to be 150 million won or $125.000? And JYP even said for an idol group to debut and have their first comeback, the management company will have to pay an estimate of 1.9 billion won. If China's digital chart can bring a lot of money, do you think it might be better for Kpop group to promote more in China.
