Like u said u started from fun. All u need to do is to find another fun. Focus on something else that suits u, if u don't have u should search for some hobbies to occupy your mind.

Recreational gamblers play for fun and spend a few dollars to have a good time. Gambling addicts place bets for reasons other than entertainment often trying to escape anxiety or other problems. Whatever issues you face, gambling isn’t the solution.

Seek help from organisations such as these:

You also need to develop a mindset that gambling would not gain you any profit and would just ruin your life. Do ask your friends and family to help you to manage your money. If you have problems with online gambling, blacklist the sites using your firewall and set a password to reset them. If you have the urge, take a moment and think about the negative impact of doing it. After several months, you can occasionally do it but restrict your sessions to a few times per months and a fixed bankroll per game.

The traditional way of getting away with addictions helps the best "The only way of getting rid of some addiction is getting addicted to something else".Also this strategy was helped to get drug addicts off particular drugs .Start getting busy doing other productive things like reading books,playing football or generally attending live events.Once you get busy in life doing things you won't have time for gambling at all.

It's back to yourself nobody can help your problem because only you can control of yourself. Try with a little things like dont open gambling site or dont use your PC in a weeks "if you addicted play online gambling"

Try to un bookmark all of the gambling sites from your browser, Focus on earning not wining, try to make cold storage and deposit bigger amounts of bitcoin there is you are gambling with bitcoin.

This question like how to stop smoking.. lol.
Im addicted to gambling too actually, its hard to stop..
but im doing like this. Whenever i have like 0.1 btc from any campaign, i will exchange it to paypal. So the money safe in there, i know i wont touch paypal money until i withdraw to my bank. But in real life i dont have tips to stop gambling.
Good luck..

This is a great technique to stop it.It works in all the cases but at times if someone's even unable to stop the paypal habbit they can simply transfer the funds to their local bank accounts which is a great way to get rid of gambling.

My suggestion for you is to find another hobby so you can have fun and fill your time with it. So you will forget about gambling and your addiction will steadily dissapear.

Good start is to talk about it. Keep trying to discussing your addiction. Meet some people, have look for some new opportunities you can do. This way stop thinking about gambling. Good luck.
