Fully disagree. Speculation and profit are good things, and without them Bitcoin dies. My sincere hope is that Bitcoin enables massive profits for all sorts of people. You profit when you don't pay a fee to Visa. You profit when you send money to your friend in Italy. You profit when you can buy products 2% under retail due to the lack of chargeback risk with the merchant (and the merchant profits when you buy from him). You profit when you're able to hide your money from nasty governments, and the victims of what those funds would have been spent on profit by not being victimized. You profit when you can buy whatever you want, from anyone in the world, without 3rd party interference. And you profit when your assets are held in a currency that cannot be debased in perpetuity.

All that profit, and much more, is the promise of Bitcoin and if that's not worthy of speculation then I don't know what is.

Let's hope Bitcoin continually enables greater and greater profits for you, me, and society. If not, then for what purpose do we use it?
