Using third-party services from within wallets is usually a bad idea. If you ever want to exchange your assets to another, you should either use a centralized exchange, and if you are not a fan of that, you should use decentralized swaps and platforms that are at least reputable and makes the swaps easy and quick without any hassle for you.
Ordinarily this shouldn't be a bad idea, IMO it should be one of the most trusted because for a wallet to allow a third party in their platform it means they knew or have knowledge of the team or the management of the so called N. Exchange. If he has been using the Exodus wallet without complaints all these years, he has developed some level of trust with the wallet. So he believed that what platform that's onboard within the Exodus wallet should be reputable as well. So I don't blame the Op for his decision to use the N. Exchange. Just like as @Potato chips has rightly pointed out, the attention of Exodus wallet management team has to be drawn into this case. Possibly with their help this can be resolved. Because this N. Exchange is trying to bring a bad name to their brand.
