Here’s what I’ve boiled it down to after a recent review—one piece of plain human advice: don’t let any position get so big that “you can’t sleep.”

If you can’t hold spot, it’s usually because you bought too much; when it goes up a little, you want to take profit and pocket it, and when it dips a little, you start imagining it all turning to zero.
Futures are even more direct: once leverage is on, if your position is too large, the volatility isn’t “the market” tormenting you—it’s you putting yourself right beside the liquidation line and partying.
My approach is pretty timid: first, put the money you can live on into stablecoins and slowly scrape a small pool out of it, like snacks; then cut the rest—what you want to mess around with—into a few smaller portions. If you’re wrong, admit it—don’t stubbornly hold on.
Recently, everyone’s been talking nonstop about modularization and the DA layer, and developers are hyped up beyond belief; as for a user like me, honestly, I’m just hearing it and feeling totally lost… so I have to control my positions even more. If you don’t understand the story, don’t “try to understand” by going heavy.
That’s it for now. I’m going to sleep.
