I have read that some people consider this portal a scam. I have registered there to check how it is today. Just after registering I have got more than 50 dolars (10 empowr coins), for me it looks very suspicious. I only did 2 likes as the wizards requested. BUT, these are not coins, it says that are pre-coins.
It seems you can only get coins if you sell products and services, for posting and giving likes you only get pre-coins that are not possible to cash out.
