Block9 is a great place to get started with Bitcoin. From setting up a wallet to how to buy some BTC and even how to incorporate Bitcoin into your business. Block9 is where it's at.

Block9 helped me understand the basics of Bitcoin and Stacks and I am now in the planning stages of launching an IP on Bitcoin. The information shared in the Block9 seminar helped me make a giant leap into the world of blockchain. Definitely recommend anyone that is curious to attend a Block9 seminar!

I can't say enough good things about Block9 — they've completely changed how I see blockchain and Bitcoin! As someone who was totally intimidated by crypto (yep, I was that newbie googling “what is blockchain” at 2 a.m.), I was blown away.
