Welcome to steemit & crypto! Some basic advice:
- I still think the best place to start is here: https://bitcoin.org/en/getting-started
- Find a free copy or buy a copy of Mastering Bitcoin: Unlocking Digital Cryptocurrencies by Andreas M. Antonopoulos
- Websites: Coindesk.com & Coinmarketcap.com
Cheers!
Good stuff. Thank you.
