Gambling is risky, remember you earn your coins in a hard way so protect them. Gambling is profitable only if you will play in them a good way.
So gambling is risky and it's profitable only if we play in a good way? And I am losing money here and there without knowing these facts about gambling...
It's all about understanding the game! You can't play and for sure you can't win if you don't know what is game about! Starting from the rules, to min/max bet, knowing your positions (bankroll/goals), you need to have a plan to get to the something you want! As someone said it:
Anyway, in essence I think it is the work of BTCGOSU ; to give the correct orientation to every novice or experienced player who needs it. The correct orientation is priceless.
First educate yourself, try to learn as much as you can, and then try it! It's how it goes, you risk and win/lose, you try it again and again, and if you do everything correctly you will have more chances to be profitable in the long run, if not then you will have to face with more loses than profit from you gambling sessions!
