yes, it is a good way to save and invest.
the main point is not to keep cash or assets, the main point is to involve a third party ( wife husband family member ) to monitor and control my activities. if everything is under my control I agree with you it is less tempting in the case of assets compared with cash, but if I get hooked again nothing will stop me from selling that asset or getting equity loan and gamble that money away. it is less tempting but for a gambler, it is a risk that needs to be considered.
You have mentioned options trading, I have tried it few times but I didn’t continue because at that time It was a clear form of gambling for me, especially some brokers offer forex options trading for 15 min, 5min, and even 1min. it was outright gambling compared to trading forex where it is a hidden form of gambling. If you read my posts you will know that I was shocked that I have a gambling addiction I was thinking that I have never gambled in my life but I realize that I was gambling for a few years without knowing that.
