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.
I am not sure there is someone out there who makes gambling their main income system, except for a bookie, he could get income every week from some gamblers coming to his place.
Many people said gambling is the place for fun cause very few people come out of the gambling table with a lot of money to support their families, most of them only hold their heads when they leave the gambling table.
