I don't think you need to mess your trading plans and strategies like making an increase in margin trade or leverage just to make you hfun, a passionate trader will certainly be fun with whatever plans they make, whether fixed strategy or something like that. I don't blame you if you're boring, but it looks like you don't enjoy every process in trading
I wouldn't call it fun. I think if you derive fun from trading, you must either have a lot of money that you can afford to lose, or you're earning a commission and trading other people's money so there's no repercussion for making bad calls in trading.
Passion I can understand. Even enjoyment. But I'm not sure about fun. I can enjoy something without seeing it as fun, I can have fun without really enjoying.
And Crypto? I enjoy. There's very little fun.
