The amount of money you should have is directly related to your goals and vision. If you just want to support your family then 2M SATS is enough. 100 Bitcoins are not enough if you have a vision of feeding and nourishing villages. If your thinking is big and your vision is big then billions of dollars are not enough, if your needs and desires are small then 100k is enough for you. And thirdly, if you are a slave to your desires and are desperate to buy what you want, trillions are not enough to fill your stomach.
