The current number of bitcoins is still rising in this market. There are currently quite a few bitcoin miners. This balances supply and demand in this market.
Mining is a good source of income, but in third world countries where the labor is cheap there, there you will face electricity problems and your mining will take long time. In these days demand for bitcoin is low and that why the price is not growing, although people want to buy bitcoin because of the bright future and high profit returns that cause high volume also.
