A good way to take time of reading the charts and chill. Besides, youre not wasting time if youre earning. Even if its just 1 Satoshi
You are pretty much wasting time if you are earning just 1 satoshi. There are much better ways to spend time and earn real money.
I don't know about sites posted in OP but you posted gambling site there. Earning money and gambling is big no and it is not a way to earn money.
