Do You Ever Pay Attention to When Exchanges Actually Charge Fees?
I never really paid attention to fee timing on exchanges.
Fees were just background noise — they exist, they get deducted, whatever.
But after switching between spot, perps, bots, and convert on BYDFi lately, I accidentally started noticing that not everything charges at the same moment, and it made balance tracking a little more interesting than I expected.
Spot was the first place where the timing stood out.
Market orders take fees immediately, but limited orders behave differently depending on whether they get taken right away or sit in the book for a while.
The currency switch between buying and selling surprised me more than the timing —the BTC out when buying, USDT out when selling. Not wrong, just one of those small details you only notice when reconciling after a trade.
Leveraged tokens were easier to understand — USDT both ways, no mental math.
Perps were where timing mattered the most for me.
Opening takes a fee, closing takes another, and maker/taker logic still applies.
The settlement currency changes depending on contract type, which quietly affects how your balance looks over time.
Bots made me see fees differently, not because they were higher or lower, but because automation spreads them across multiple mini trades.
It doesn’t feel like fees happen — they just accumulate in the background.
Convert was the opposite experience — the fee was already baked into the quote.
Nothing to reconcile afterwards, nothing to think about. None of this is groundbreaking.
It just made me realize fee timing is one of those things traders don’t talk about but quietly learn through usage.
You don’t notice until you trade across products. And once you do, it’s hard to unsee.
