Hi Ribuck,
like I said before, there is a big difference between buying an electronic device like a TV.
Lets just say you bought a TV last year (2013)with bit coins. The TV was worth $1,000 and you paid in bitcoins. This year 2014 the value of bitcoins has increased that much that if you did not purchase your TV, you would now be sitting on a fortune and be very rich.
Now lets just say you bought a TV with normal dollars, sure there will be a newer model next year which will be better thank your old one and maybe the same price. But you can sell your last years TV and get the new one. you are not really taking a big risk. But with spending your bit coins you are taking the risk that your coins will be worth an enormous amount more in a years time.
Comparing not spending your bitcoins to waiting till next year to buy your TV is not relative at all.
Do you understand my point about the possibility of todays bitcoins being worth much more tomorrow and by spending them you could be losing out.
