There is no rush, but one of the cool things is you can send a "zap" of money to anyone that has this configured. You can send a fraction of a penny's worth of bitcoin as a "like". You can also send a hundred dollars worth or more if you want. That sets up a value for value situation where we can pay content types directly, no middle man, no permission needed. The Primal Nostr client has a wallet built in, but there are lots of options. This is techy for sure, but that's the fun ha! You've got a whole new world growing here, enjoy.
