If you have bitcoin and you aren't spending any of it, you are not helping the cause whatsoever, and ultimately just hurting yourself.
Not quite. Individual self-interest conflicts with group self-interest. As long as people expect the price to dramatically increase, they won't spend. Virtually no one will spend coins out of altruism to the group of all bitcoin holders.
Instead of buying stuff with cash, buy Bitcoins and use them straight away. You can still hoard whilst promoting BTC.
this is another place to use bitcoin as a currency instead of as an investment which is great. Things will start to get really interesting when stores like this can actually use the btc rather than convert to $ immediately. Once they can use BTC to pay their suppliers, or their employees, then BTC will truly be a real currency and the overall value will rise.
I agree. I hope this will happen in the future.
