Most people compare crypto exchanges by maker/taker fees.
That is useful, but it is only the visible cost.
The real cost can include:
\- spread
\- slippage
\- funding rates
\- conversion costs
\- withdrawal route
\- deposit method
\- liquidity
\- execution quality
A platform can show low trading fees and still cost more if the spread is wider or the exit route is messy.
For me, the better question is:
What is the full route cost from deposit to trade to withdrawal?
Not just:
What is the fee table?
What hidden trading cost surprised you the most?
