Which crypto to fiat pairs are most profitable?

[Gretel]

When exchanging crypto to fiat, do you usually go with BTC, ETH, or USDT? Which one tends to give the best rates and lowest fees when withdrawing?

Rates differ depending on demand and liquidity. For example, BTC is widely accepted but sometimes has higher fees. USDT often has more stable and predictable conditions. I usually compare before making a move. Sites like https://www.trustchange.com/ help by showing all pairs and their rates in one place, so I can see at a glance whether it’s worth exchanging USDT or BTC at that moment.
