Lessons 9 to 12
09 halving
The halving
The reward for a new block halves every 210,000 blocks, which is why the total stops just under 21 million.
10 node
Running a node
Checking every rule yourself with free software on an ordinary computer, and what a node can and cannot see.
11 backup
Backups
Writing down recovery words, paper or steel, where to keep them and how to test a backup before you rely on it.
12 scam
Scams
Giveaways, fake support, recovery services and pressure tactics: the tells, and what to do if it happened.
Try at home
- Write a practice backup of a test wallet on paper and restore it
- Read one scam warning from your national fraud line
