Right now you could afford a bar of affordable hand soap for around 1-3 POB depending on your demographic, maybe you could sell that and get some soap!
you are right we can buy a good quality soap by selling 3 POB.
but i would love if a day comes when we can directly buy a soap with POB.
think of a day when these tokens can directly be exchanged for goods and services. that will be the biggest success for Blockchain and Crypto currencies.
