It's easy for you to say it but it is actually hard to do. You know avoiding using your Bitcoin in stuff such us gambling or fake investment is hard because they are the ones that are widelt available for Bitcoin. When you go to the internet it is hard for you to find where to spend your Bitcoin except for Gambling sites and new hyips.
That is why you need to have self-control first so that you will really be able to avoid the temptation to gamble or to invest in HYIPs, There are many ways to stay away from gambling but if you can't control yourself to do those way then you will still end up gambling or investing in HYIPs.
Self-control really is hard especially when someone is already addicted. I had a minor addition back then but I overcame it. What I did is to always think that I don't have money. I don't even have money to eat. So I can't gamble because I don't have money! That's what I kept in my mind so I stopped gambling. How this helps someone else get over their addiction.
