Not many. Daytraders at best.
No guarantees, it would be subject to NuLaw. We have seen that it is now weak, underdeveloped and therefore not trusted much.
Government's paper money is also a mess and subject to the whims of a small group of people (think FED, Goldman Sachs and the likes). Most of the people still trust it though
Yes, a lot of them are apparently as they still investing in dollars, euros, yens etc. while the printing goes on and the debt increases with stagnating economic output. Some say the system is broken, some say it still works. If it doesn't we likely end up with a world war. Although there are some with interests in that, I believe that the majority still tries to prevent that. But I'm getting off-topic.
Let's proof that when NuLaw is actually followed and understood by the shareholders and the right incentives are put in place and clearly communicated. I would say 50/50 that it may work assuming a couple of things with better governance and less centralisation change soon. Worth a chance and an interesting experiment. Only reason I'm still here.
Not if it is right?
