How do you react when you come across a project saying that it is not charging any fee, e.g. a swap or a DEX which does not collect any fees. Do you take it as an advantage or it does not look serious enough to you?
I don't think there is anything wrong with it, it could be there own competitive advantage, there are some projects that started and dash money to people to use their platform, PayPal is one that comes to mind. The most important thing to check is if there are legit and won't disappear with your money
