Use nostr.mom (has spam protection + popular) and cloudnull.land (free with little to no spam) until you get zapped enough. I got 2-3 paid relays by nice people.

I still need to set up an address for zapping ability. I tried getting Wallet of Satoshi but I think it might require Google services framework on Android which I don't have installed and the app crashes for me. 😕 For now I can just paste invoices generated from Blue Wallet.
I could always send myself the sats but I'm resisting sending even a few bucks out of cold storage (which I know is silly).
