There are only 38000 blocks left until the next halving. What will you be doing? On the average there are 144 blocks found per day. So in roughly 263 days. Planning a halving party is tricky since you can't really book a venue or an event since it could be off by a few days. It requires flexibility with a group of like minded people who can get together on a moments notice. Perhaps at a pub, or in a park?
