I don't follow. If some miners switch to a new coin, then the Bitcoin difficulty will drop and the remaining miners will make more coin. As long as the value of bitcoin doesn't crash, it will reach a new stable point with a lower number of miners. How is it "winner takes all"?
This is true on a flat field yes. but if some player/s have the ability to bias the field then it all goes to shit.
"Regulated" is a myth. It implies a central regulator, and that doesn't fit with a world currency - an internet currency.
Regulation is not a myth, I wish it were.
We are in agreement, You don't like regulation, I don't like regulation. We are probably not in the peak of the distribution of like/hate regulation when considering a large sample of potential future users.
The viruses that are coins compete for users and miners. The primary entrance being the miners of course. Are you suggesting that all miners hate regulation so much that truth and liberty is their prime directive? I can imagine (call me cynical) that the prime directive for many will be profit, sure they will wear the bitcoin t-shirt, but will they make sacrificial moves if it comes to the crunch? I'm sure some will, but when the players are anonymous, the game tends to run in a very selfish manner.
It is quite conceivable that the downfall might be as simple as a new pool that has fiat backing, over time it would absorb all hashpower.
in a nutshell: whose got the deepest pockets before the game begins?
