the majority of Bitcoin is just involved in stock-like system.
Yes, for a short term. The long term will slowly steady out as we get closer to 21 million. I noticed that most of of my friends are supporting the bitcoin commodity which is fantastic. They are mining as well. We will have even more mining players in the system thus, the calculation to mine blocks will dramatically reduce as more miners appear. Although, the difficulty blocks bound to get harder to mine which will scrape the lower end miners. They will not able mine very well and not very efficient plus, it's just a waste of time.
But good hackers/engineers will have an advantage. That is REALLY what I like about Bitcoin - not financial crooks, that can do nothing, but down to earth practitioners will benefit. What a relief for a change, after all the "outsourcing" done by greedy assholes not willing to consider implications of their unlimited greed (defined as a desire to improve your position 10 times at the cost of making position of 1000 people 10 times worse). That is generally road to nowhere, whereas Bitcoin is a road to sanity.
