Hey there, sounds like an awesome Bitcoin meetup! I'm always excited to hear about events that bring together fellow crypto enthusiasts. The game sounds like a fun way to kick things off, and the prizes are a nice touch.

Privacy is such an important topic in the crypto world, so I'm glad it's being covered at your meetup. It's crucial that people understand how to buy, store and verify their own transactions securely. Running a pruned node is also an excellent way of maintaining privacy while transacting with Bitcoin.

I'm familiar with RBF (Replace by Fee) & CPFP (Child pays for parent), which are both incredibly useful features when it comes to speeding up transactions. And it's great that @calmhodl will be discussing privacy tools like Whirlpool, stonewall X2 and ricochet - these can definitely come in handy!

Overall, it sounds like you have quite the lineup planned for your event - wishing you all the best!
