I make monthly purchases, and while some goes to long-term savings, some also goes to vendors that accept bitcoin. I pay for a personal paid relay, access to nostr.wine's inbox relay, access to nostr.wine's filter relay, top-ups for nostr.wine's cellar relay, expenses related to my lightning node, and a monthly top-up of my zap fund. So, I'm contributing to Bitcoin's ecosystem while also directing sats to my cold wallet. I find it easier to manage by having a system, and just adhering to it. If you do, you'll cover your bases pretty much automatically.
