Even if the crypto markets tank more from here, Steemit will continue to have value because regular users will continue to post and use the platform. Just look at how far Reddit, Facebook and Twitter have come, and their users didn't get a dime of the platform's profits!
On ordinary social media platforms, the users, along with their precious ($$$) info ARE the product, whereas on Steemit, the product is the content and interactions! Big difference!
