There are many well-known cryptocurrency exchanges. While the standard trading interfaces of these cryptocurrency exchanges can overwhelm newbies, especially those with no stock trading experience, they also offer convenient and straightforward buying options.
I use online exchangers and the BestChange service to select the best exchange conditions. Here you can find information from more than 440 exchangers. On the BestChange website you can easily find and select exchangers for exchanging usdt to usd https://www.bestchange.com/tether-to-dollar-cash.html or for any other currency pair
I like the conditions on the Changelly exchange. It has high transaction speed and low fees. At Changelly, I exchanged BNB to BTC https://changelly.com/exchange/bnb/btc
Changelly platform can offer you competitive rates, low fees, the highest security standards, 24/7 support, and more!
