I use River since it’s the easiest way to DCA in my state. Highly recommend!
Everyone knows about Strike but nostr:npub1xkere5pd94672h8w8r77uf4ustcazhfujkqgqzcykrdzakm4zl4qeud0en is a sneaky exchange that checks all the boxes in my book. If Strike is your primary definitely check out nostr:npub1xkere5pd94672h8w8r77uf4ustcazhfujkqgqzcykrdzakm4zl4qeud0en always good to have two solid places to DCA and be able to withdraw via onchain or lightning easily. Especially if one has an issue. Always have a backup to stack hard on a big dip.
