the best thing to earn bitcoins is participating in signature campaigns that pay you some decent money for posting in my opinion, also to earn money you shouldnt lose it on gambling website too, thats the key thing in my opinion
Agree with you about staying far from the gambling and casinos sites, because it's risky method, but i think to growing up our coins we have to diversify our methods, signature campaign is good tool, but we can sell services and goods for Bitcoin too, it's profitable method in my opinion
Agreed: trying to grow your BTC by gambling is the worst idea.
