I am a simple person, my income for the month is $ 300 (salary).
You do not sound like you have the discretionary income to be gambling on dice sites.
As always, one should never gamble with money they cannot afford to lose. You do not sound like you can afford to lose anything if you are only making $300 a month!

I think you need to reevaluate your gambling before getting into serious financial trouble.
this sites is earning? haw i can earn? here is some video tutorial?
I'll tell you right now... There are no "tricks" or "techniques" or "eBooks" or "systems" or "video tutorials" that will be able to guarantee the ability to "earn" money from gambling... unless the place you're gambling at is fundamentally broken and/or there is some way to cheat the system.
Gambling should be treated as "entertainment"... it most definitely is NOT a way to make a living... unless you actually own or work at a Casino!

I'm fairly sure there is a joke that goes something like "How do you make a small fortune by gambling?... Start with a LARGE fortune!"

Trust me on this, I work at a real life casino. I have access to all the numbers and statistics... they do NOT make good reading for the players.
