Nowadays the Internet id prefilled with exchanges of various types. As for me, the best ones are Binance, CEX, Coinvase, and Localbitcoins. They are different from each other, so you can choose one by checking available features and trading pairs. Currently, the exchange of my desire is https://cexbro.com/. Though,  the time and experience will show if it is actually as good as it is supposed to be.
