Rate history from Coinfuty market data: hourly closes for the 24H and 7D views, daily closes beyond that. USDT is a dollar stablecoin and is held at today's price, so the line tracks ADA. The live rate at the top comes from our own price sync, so the last point can differ slightly.
What you actually receive, exchange by exchange
The rate above is the mid-market rate — no exchange gives it to you. Every conversion pays a trading fee, and moving the result to your own wallet pays a withdrawal fee on top. Both numbers below come from our fee database, not an estimate.
