I too also spent alot of money on ads on facebook for my personal training studio, I gained a lot of traction using facebook. Honestly, their ads are amazing and if done right can make your business so much better!
I love steem and yes they pay, however they are two separate platforms and no one wanted a dime from Facebook until they started getting paid from steem. However if they do decide to integrate cryptos, I dont think it will be anything like steem.
