Here's my best Bitcoin pitch to the Rich World's working and middle classes, who can only afford to buy relatively small amounts.

1) It's a currency hedge against rising government debt.

2) It's at least price-stable in the mid-term, so you can put your savings there and decided how you want to spend it at a later date. This is smarter than rushing because of inflation.

3) It's protection against possible political, religious, or personal persecution, because it's harder to confiscate by court order.

4) It can buy you time, later, with your loved ones, by allowing you to, for instance, move house or afford better medical care.

5) It is highly portable, so you could send it to someone in need, on the other end of the world, within seconds and 24/7.

6) You can spend it in tiny amounts and receiving something worthwhile for it.
