I would like to know how you do, I have an account but I have no knowledge..

I lose, I recover, I lose, I recover, and so on all the time, but I earn 3 or 6 dollars a day just by betting 30 dollars divided into 2 coins, $15 and $15.
I need to control my emotions to exit earlier, I always end up winning over 10 dollars. But those who don't take risks don't win.
As I said before, the first thing you need to learn is to lose less, not to win more.
You should take this as a hobby and you will lose your fear, you will see.
