The controversy of how you save more by converting or selling in spot, here I explain why spot is better.
Let's compare Convert vs Sell in Spot on Binance using your example of changing $2000 in BTC to USDT, focused on which one charges you less:

1. Convert

It does not show a direct commission, but it gives you a less favorable price.

Binance earns with the "spread," which can be between 0.1% to 0.5% or more in volatile markets.

Realistic example:

Real BTC/USDT price: 60,000

Price in Convert: 59,800 (spread of 0.33%)

You receive: 2000 / 59,800 = 0.03345 BTC

In that case, you lose about $6–10 due to the spread.

2. Sell in Spot (Market)

It charges you a fixed commission of 0.1% (or less if you use BNB to pay).

You use a market or limit order (to have better control of the price).

Example:

You sell BTC at the real price of 60,000

You receive: 0.03333 BTC × 60,000 = $2000

Commission: 0.1% = $

Conclusion:

Selling in Spot charges you less commission in most cases.

Converting is easier, but the price is a bit worse, so it costs you more without you realizing it.
