It's unbearably stuffy weather today, and the traffic jam on the road made the coffee cold... Suddenly I thought about my recent trading: can't hold onto spot positions, and my futures got liquidated. Honestly, it's not about the direction; it's that my position size is too "confident."

Here's a straightforward rule I tell myself: don't let emotions decide your position size, decide based on the "worst-case scenario." If you want to chase after spot, go ahead, but only with amounts that you can pretend to be dead for a week if it drops. Futures are simpler—before opening, assume you'll be wrong three times in a row, and ask yourself if you can survive. If you can't, don't open the position. I'd rather earn a little less than blow up my account on a single overconfident move.

Recently, with social mining and fan tokens—this "attention equals mining" approach—I see it as just giving FOMO a new skin: attention comes quickly, and it leaves just as fast. The incentive structure flips over, and all that's left is who can catch who. Anyway, I’m turning down the leverage a bit to keep my mind clear.
