Probably might not happen.. but if it happens might take over 100 years or another 2 world war..
of course, will never happen. Imagine how easy it is to earn $ 1 when 1 satoshi worth $ 1. I thought this would never happen. despite the war going on though dollar was the strongest currency so it is unlikely the dollar will be worth very cheap
If a satoshi was equivalent to 1 dollar you can bet that obtaining a satoshi will not be as easy as it is today, you can earn a few hundreds of satoshis through faucets, but if satoshi was worth a dollar and faucets still existed by that time you can be sure you will need to claim hundreds of time from the faucet just to get 1 satoshi.
