I think I received 7 coins for this 1st place witness.
Even when your home or just sitting still you can be mining coins with this system. Just click the button under the pick ax and it will mine automatically for you as long as the app is open and active.. the keep your eyes open for the little blue symbols that look like stars in the upper left hand corner
and when you see them click them and then quickly check off the boxes that pop up in a new window. 
The faster you do this the more you will be rewarded .. the first 200 receive the rewards
The following is a YouTube video from their company :
My next step is to get one of the sentinels that are spoken about in this video.
The most interesting thing about this project is the way you can use your coins.
You can have them sent to your private wallet to be used like any other #crypto Coin, use them as money with anyone else who wants them in exchange for their goods or services, or you can redeem them directly to the company for merchandise they offer or #Bitcoin or #Ethereum #erc-20 tokens., or #Ethereum.
The way I see it , if you have a trucking business or run Uber or a taxi cab this could really turn out to be a real money maker . Imagine if you owned a fleet of busses or trucks and had one of these set up with each driver? Yes they pay on referrals as well.
Below is a quick video explaining the basics, it is not mine but I thought it would help break the system down . I’m still learning about this too.
The company at XYO offers quite a set up to get the job done as well.
As for costumer service , I had an issue that needed more clarification so I went to their Twitter account, followed them and then asked my question and in about 5 minutes had all my questions answered.
I’m looking forward to this project and if you think this is something worth getting involved in use my referral link when signing up with them and we can both profit from this
Definitely an app worth checking out. Lets you earn crypto!
