BTS and BlackPink Niche

There are so many fanatics of BTS and BlackPink nowadays so I recommend making a website dedicated to this korean groups, promote it to social media and add merchandise like tshirts, mugs etc. Even just the Mcdonald BTS wrapper are sold for $10 here in our place. Content of the site is up to you whether use a spinner and copy the contents of another site or use your own words.

I bet if someone make a BTS cryptocurrency, a lot of crazed fans would invest in it.

BTS has extensive marketing. It's difficult to identify real followers from marketing channels. I wouldn't invest in such a niche.
