Look at the rewards sensei, from 89$ to 92$ it went up becoz steem went up in price per unit. From 0.92$ to 1.10$, everything here is volatile.... do some research about cryptos.

Ohh I see!!!

googled it? Steem is a crypto coin that goes down and up in price(every crypto coin) its an investment. So when you do steem, you are paid in an instant investment that you can sell for yen, dollar or any currency you like.

I see!
Your japanese grandpa will do study it! ;)
