Welcome!
Few things you should know:
1. get a check mark in #Nostr, there are few options, I suggest nostrcheck.me, once you get it, edit your profile and update your Nostr-Address, not having it will hide you in some clients
2. follow hashtags, a good way to find like minded people
3. think of your nsec as your Bitcoin private keys, act accordingly
4. chose a client that respect your privacy, meaning, you can sign in with a Signer protecting your nsec, it has TOR built in and above all, you can manage the relays you use. I suggest nostr:nprofile1qqs24yz8xftq8kkdf7q5yzf4v7tn2ek78v0zp2y427mj3sa7f34ggjcpzamhxue69uhhv6t5daezumn0wd68yvfwvdhk6tcppemhxue69uhkummn9ekx7mp0qyg8wumn8ghj7mn0wd68ytnddakj703s8dt t
5. add your lighting address in the profile so you can get zap, few options out there, I suggest nostr:nprofile1qqst4qyeqenw7zm0fwjsty68h6cnys5jre2xd8ngqpjv5a2j26s78fspzemhxue69uhhyetvv9ujucm0d9hx7uewd9hj75a0pev for most people
have fun!
Thanks, I can't see my nsec where would I find that

Hello, I'm in a similar situation, just getting to know nostr myself.
I understand completely having dedicated the last 25+years to my art, well done for staying the course and keep going, I look forward to checking out your art.
My understanding is you can work out the price you bought either as first in first out or you can do an average if all purchase prices, none of which is easy for accounting purposes in itself making a case for removing the cap gains tax on #bitcoin
Just trying to understand Nostr and how it works, is there anyone out there, I'm a UK based guitar maker looking to use nostr to promote my craft. #guitars #luthier #classicalguitar
