You are the new CEO of a three-branch community bank with $250 million in assets. Fifty years of real banking history are coming: 20% prime, the thrift crisis, FDICIA, the internet, 2008, zero rates, the 2023 rate shock, and the rules that finally let banks touch Bitcoin. Every decision moves a real balance sheet. Keep capital above the line, keep your depositors' trust, and see what kind of bank you have built by 2030.
