If you fill the bitcoin bucket on a regular basis, and the price continues to increase as anticipated, it will become increasingly difficult to acquire a whole bitcoin (likely out of reach for most people at this point), but if you manage to get to 0.1 (or 0.25, 0.5, whatever...) and bitcoin really goes to $10M or $40M or $100M ... that leaves you with a healthy amount of wealth, as time goes on
