A trading venue with an order book where buyers and sellers set the price. Cheaper at volume, but requires an account and trading knowledge.
In more detail
An exchange sets the price through a buyer/seller order book and is cheaper at volume, but requires an account, verification (KYC) and trading knowledge. An exchanger is simpler: a fixed rate, no order book, for the one-off task of «swap and withdraw». For a simple exchange a beginner usually finds a monitored exchanger more convenient, and an exchange for active trading.
