Because too many people are doing nothing to promote Bitcoin to other people. We will not see a massive increase in the price from current Bitcoin hoarders, because most of them have already bought their share of the coins. I buy much smaller amounts on a monthly basis now, than what I did when I entered the scene many years ago.
Some people buy and sell during normal trading, but it is not new fiat money coming into the pool, only old money being circulated. What are you waiting for, get out there and promote Bitcoin to new people. ^smile^
Yes, but according to my theory if the number of people will increase and the amount of bitcoins will decrease per user, like suppose everyone in the world holds 0.0001 btc then yes the price would be around 100k $ per bitcoins but at the same time there would be no price changes at all and hence no price trading.
