Today, staring at the blockchain until my eyes hurt, I feel like I'm watching a "never-ending" magic show: you think it's an arbitrage opportunity, but when you click, you realize you're more like giving someone a tip...

The sandwich thing, honestly, is just you acting first, and someone else quickly snatching the opportunity, with fees + slippage taken together, leaving you with nothing to smile about.

Recently, there's been talk about increasing taxes and compliance in certain regions, tightening and loosening at different times, causing deposit and withdrawal expectations to shift.
Everyone gets more anxious, and the more anxious they are, the more likely they are to chase that tiny "spread."
Anyway, my current strategy is just one word: stop.
Stop, observe, pause...
Let your mind cool down first, or the next move might just be paying tuition to miners and bots.
