I'm a big believer in Bitcoin, both as a currency and for what it can potentially stand for and how it could possibly revolutionise the banking system, and it's because of this that I'm holding my coins and speculating on the future price. If you think Bitcoin is going to keep growing, then it's wise to hold on to your coins as the value is likely to increase in many multiples. There's nothing much I'd like to buy with Bitcoin at the moment so I don't just want to fritter them away on crap, but I would be more than happy to spend my coins when it's possible to do so on the highstreet and in many online retailers for stuff I actually want. I may spend some coins if I come across an establishment accepting them as I'd like to do my bit, but I can do my part in other ways by promoting Bitcoin and spreading the word etc.
I am not arguing that the speculators are not important or useful to the Bitcoin economy. Yet currently the speculators are probably out weighing the actual users of the currency.
I don't see what the problem of that would be, but what figures do you have to back this up? Any comment on the number of spenders vs hoarders seems to be based entirely on assumption at the minute.
