A trend has been started that bitcoin is now used only for raising income by buying and selling it but we are ignoring its most important fact that it was created to be used as currency and if it can be used as the currency it would really help community to enjoy its eases and regions who are accepting btc must have to start it as currency this will automatically boost user no's as well a prices,
This is one of the biggest problems with bitcoins currently. I think even the developers did not wanted bitcoins to be seen as an investment medium when they launched it. However, as the prices started going up, everyone became greedy for money and forget about the real use of bitcoins. When we have price stabilize completely, people will start using it for buying/selling more often. Current situation is like everyone wants to get paid in bitcoins but no buyer want to pay in bitcoins as they think that the value of accumulated coins will increase.
