I have to disagree.
The Exchange of Bitcoins is becoming more and more decentralised. From the all powerful MTGox, to 4/5+ main exchanges in just 12 months. Last year saw the introduction of the first Bitcoin ATM's and this year mobile bitcoin vending machines costing less than $1000 will erupt onto the scene, all of this in less than 12 months too.This year we will also see 'decentralised exchanges' for the first time ever. It is literally an EXPLOSION OF DECENTRALISATION.
From one exchange to five exchanges is not a change which could be used to establish your argument. Moreover, the tendency is more and more exchanges complying with government policies. Since such policies are similar across different jurisdictions the exchanges dealing with BTC will adopt practices defined by a central body of governance.
Um yes it is it's a huge difference! You are completely wrong.
Having 5 major exchanges in 5 different jurisdictions vs. 1 main exchange a year ago, a 500% increase, does establish my argument.
Last year China virtually shut down the biggest exchange BTC China but because Bitcoin had 5 other exchanges in 5 other Jurisdictions, Bitcoin was able to absorb even that blow.
What about the open source < $1000 mobile Bitcoin vending machines? The equivalent of thousands of mini-exchanges in hundreds of countries? Will all of them have to comply with your 'similar across different jurisdictions, government policies?'
What about the new decentralised exchanges, will they have to comply with your 'similar across different jurisdictions, government policies?'
Also you only have to look at gold to see that BTC will never 'adopt practices defined by a central body of governance.'
They are trying to ban and tax certain gold imports into India, though they can limit it to an extent it has just resulted in a 1000% increase in smuggling and decentralised the market. (
http://www.youtube.com/watch?v=IpdoRUMeshw Some Indians are even willing to sift and swim through literally miles of faeces to mine/bring gold into the country, if they can't stop gold they can't stop a crypto-currency that's dealt with the centralisation of mining issue.)
More and more secure decentralised solutions are being developed everyday.
Decentralisation is the future.
