i wonder: if Bitcoin will become the main coin, what will happen to the money we are using now like us dollar?
Altcoins like dollars will still be useful for paying off your govt (aka taxes), as well as anonymous transactions for booze (oh wait, thats legal now), weed (oh, wait...), hookers?, crime?
Worst case, shredded and fluffed they make great filling for pillows as the paper is actually a high quality cotton hybrid.
