I understand how you feel, especially when mining isn't that profitable anymore, there are few people that I helped to set their miners up and they bought the miners for passive income only, the idea of holding for long isn't in them, and when Bitcoin mining isn't that profitable anymore they decide to look for other means, they even start selling their miners.
In your own case OP, it seems you got tired of mining, just like these people that I helped, the mistake I see here is going for gambling when you can learn some else, something based on skills, which I believe will give better result than something that's all about getting lucky.
You choose the wrong niche, learn from it, and a piece of advice for you, it's better to be in mining right now than to stop mining, if you still have your equipment you better fire it up, because very soon, maybe after the bitcoin mining, you will see how profitable Bitcoin will be again, the value might be times three of what it is right now.
Why is mining no longer profitable? And I also didn't see the OP mention that he stopped mining altogether. What I saw him say was that he got addicted to futures trading and then gambled and lost a significant amount of money. It can be said that he was attracted by the large profits from futures trading and gambling and forgot about his mining job.
Those who can maintain mining until now have had a lot of profits, they will not easily ignore a field with that passive income, IMO. I believe the op is still mining bitcoins regularly.
