Umm, yes a rather special group does issue the currency in Bitcoin: the miners with enough state fiat capital to invest in the increasingly expensive equipment required to mine Bitcoins.
The underlying Bitcoin implementation is fine, but I find the mining aspect hugely problematic. Bitcoins should been distributed freely to people that want them so as to provide everyone an opportunity to be part of a financial reboot. Sadly Bitcoin went down the road of having engineered inequity and is as morally bankrupt as the system it seeks to supplant.
My first Bitcoins were mined on a machine that my wife had bought me to play games. This was back in Nov 2010. It took about 10 days and was worth (then) something like £10. The machine was 'free' in the sense that it was already in the living room before I had ever heard of Bitcoin.
When I first splashed out in Jan 2011 and ordered parts for a 3x5870 rig, I was taking a risk. I took another risk to buy my next mining machine. There was always the possibility that Bitcoin would never 'make it' as a technology, that I would end up with an expensive pile of hardware and a credit card bill to settle. As it tuned out Bitcoin did well, the value went up, but the value could have dropped to zero and Bitcoin could have been relegated to the list of good ideas that never took off.
Sure, I sold coins, bought more GPUs, mined more coins, sold more coins, bought more GPUs etc. Anyone could have done the same.
Anyone who wants to can do the same now - there are still used 5870s on eBay even though they are no longer made. Good mining cards. Yes, specialised mining kit is expensive, but small scale mining can be, and I suspect is, a profitable sideline for anyone who is willing to take the risk involved in a graphics card upgrade for their PC.
What would you propose for a different security mechanism for a currency like Bitcoin? How would you distribute it to interested people fairly?
