I paid for nostr.wine.
Do u think its needed to pay for more than 1 paid relay?
You can check list of paid relays here
If you want some opinion, i think currently nostr.wine has offer more than other paid relays. They have multiple servers (Europe, Asia, US) which automatically choosen by your IP address. They also have extra useful features https://filter.nostr.wine .
You can check their sites for more information. :)
