If money could go from gold to gold bank notes to money to cards, do you think that there could be another form of money that could surface through the years?
Many are hopeful that cryptocurrencies will take off, but the technology has been around for decades. I am one of those hopefulls, but asking people to change the money they are paid in and spend with is much harder than asking them to change social media apps - and that is difficult enough as it is!
