1. Know when is the right time to stop playing.
2. Set limits and monitor your money.
3. Safeguard your budget.
The best gamblers I know are constantly vigilant and always evaluate the balance between losses and gains.
And The best advice I could give to someone who wants to start gambling is probably to never start gambling to win. It's definitely the worst approach that in the long run leads to the financial ruin of any novice gambler.
Dont play for money but rather focus out on entertainment because if you do really let yourself fall into addiction due to greed then you would really be finding some problems
later on.
Be wary on your actions because it wasnt intended to make you rich but rather this serves as purpose for entertainment or enjoyment and not a source of income.
Once you do have this mindset then you wouldnt really be putting yourself in harm.
