Been DCA’ing with nostr:npub1ex7mdykw786qxvmtuls208uyxmn0hse95rfwsarvfde5yg6wy7jq6qvyt9 every two weeks. However if I know that I’ll be doing it every two weeks in perpetuity is there any reason not to use nostr:npub1xkere5pd94672h8w8r77uf4ustcazhfujkqgqzcykrdzakm4zl4qeud0en for their fee-less structure? Is there some sort of catch that I am missing here?
