I suppose that once mining is completed, the price would then increase to a point that it would become more stable.
You can try the following link http://www.bitcoinblockhalf.com/
Total Bitcoins in circulation: 16,724,763
Total Bitcoins to ever be produced: 21,000,000
Percentage of total Bitcoins mined: 79.64%
Total Bitcoins left to mine: 4,275,238
We have only 20% of the bitcoins left without mined. The complete mining would be within long period of time accordingly.
