Re: Legitimate uses for Bitcoin ?
ISTM that you could make a far better case that cash is unnecessary than Bitcoin.
I really hope that more and more regular transactions will start being made with Bitcoin so that control is taken away from banks and other financial institutions, and exchange of money ceases to incur any overheads. As it is, a percentage of what you pay for goods and services goes to the banks or card organisations (even if you pay by cash). When you add together all the payments made to the financial parasites in the chain between manufacturer and consumer, it adds up to a sizeable chunk of the price you are paying.
