That's the problem with this currency I think, people want to hold on to it as long as possible. For most people it is more of a long time investment then a currency to spend and exchange... This will only slow down the mainstream adoption process in my opinion. Bitcoin is not stock on the stock market...

Who would want to buy for example a coffee in a shop with their BTC if they almost know for sure the value will double in the coming year?

But I have to admit, I have bought some BTC for exactly that purpose. But idealogically, it's wrong...
