Conversely, it is never recommended to use closed-source wallets like Atomic Wallet for managing your keys and transacting. In closed-source software, it is impossible to verify the claims wallet developers make regarding the security or anonymity of their wallets. For example, we can't be sure that seed phrases a wallet presents are really random and that they aren't stored somewhere in their database waiting to be maliciously spent by evil actors. When you use such a wallet for storing your keys you have to trust devs are honest. And even if they are honest, it doesn't make their wallet more secure because, unlike in open-source, there are always fewer people auditing the code in closed-source software. You also can't be sure there are no backdoors in such wallets that are aimed at breaking your privacy or deanonymizing your transactions. They might be collecting your addresses, your transactions, your system information, and your IP address (you can't be sure that the Tor connection isn't vulnerable in their implementation). All this information may be collected, analyzed, and sent to authorities for whatever reason.
