5 BTC lets the wife and I retire to our off-grid farmstead. 10 BTC lets us start farming the land almost immediately, 15 BTC gives us a leg up on the future. I don’t need, or want, much though, so once we hit that 5 BTC stack, we are outta here regardless. Off to live that sweet, sweet life off off-grid ignorance and bliss where the satellite internet is down more than it’s up. Damned solar flares. 😎
