BitCoin could automatically send random coins to a new address at random times. This would make knowing a coin’s lineage useless to an attacker, since any of these new addresses could be actual people.
Then what if you’ll keep running Bitcoin long enough? Will you get broke? (Or change the “random payment” amount to be very small.) And I thought the transaction amount was public anyways? Because if it is, then it’ll make the function useless since any attacker could just check if the amount transferred is higher than the “random payment limit”.
I dunno, sounds like a bad idea to me.
