Often when I buy a small amount of bitcoin it crosses my mind that the person on the other side of the trade may well have bought it at $100 bitcoin.

Then I remind myself of a couple of things-

1. Anyone buying at $100 bitcoin might well in turn have bought it from another party who got it at $1, or less

2. If the seller to me wants that same amount of bitcoin back, they’ll have to buy it at todays prices, or mine it.
