Welcome to the future. Get a Lightning wallet for your profile to get the full Nostr experience.
newbie here! which wallet do you suggest and how do I set that up?!
The most popular custodian wallet is Wallet of Satoshi.
Another good custodian option is https://getalby.com because they offer a few extra services. There is a cool way to connect GetAlby with Zeus wallet for your mobile device…and/or, if you live in the US, get Strike https://strike.me
Thanks man!! Glad to be a part of the future!!
