Rotating shop-style events like Dawn Market work best when you go in with a plan, since the available items change over time and impulse spending on whatever's currently shown often means missing something more useful later in the rotation.
Scout before you spend
If the market rotates on a visible schedule, checking what's coming up (or has recently rotated out) before committing your currency helps you avoid spending on a mediocre item right before something you actually need appears.
Prioritize items you can't easily get elsewhere
Market-exclusive items are worth prioritizing over items that are also available through normal gameplay — spend your limited market currency on scarcity, not on convenience for things you'll acquire naturally anyway.
Don't let currency expire unused
These event currencies are almost always time-limited. If the event is ending soon and you're sitting on unspent currency, it's better to buy something moderately useful than to let it expire and gain nothing.
Compare against your other active events
If Dawn Market overlaps with another active event competing for your attention and currency, decide deliberately which one deserves priority rather than splitting effort evenly across both by default.
