Atomic swap operates in a fully decentralized way, which allows you to get rid of two of three fees at once.
You do not have to pay intermediary fees (stock exchange or exchanger) for crypto transaction. Secondly, the wallet itself does not require any payment for transactions. You only have to pay a fixed network fee, which does not depend on the amount of the currency exchanged.
