Russian Ruble drops 12% in one day.

According to wikip:
"Break-even (or break even) is the point of balance between making either a profit or a loss."
I agree with the wikipedos: Breaking even has nothing to do with being able to pay the mortgage or balance a country's budget.  
If Libya can charge more for a barrel of oil than it costs it to get that barrel out of the ground, Libya is doing better than breaking even.  Its other expenses are neither here nor there

Have to agree with you here. Still, that doesn't change the fact that oil-producing countries suffer from falling oil prices

If it costs $30 to produce a barrel of oil in country A, and $70 in country B, would oil price dropping to $60/barrel affect both countries equally?
Of course not.  Country B would have to sell its oil at a loss

-snip-

Right. Even if it cost country B $59 to product/mine a barrel of oil the effect of $60 oil would not be the same. Country A would see a much smaller decline in net oil revenue then country B

In your example country B would need to stop mining oil until it's price rebounds for a somewhat long term before it would make sense to resume mining which would result in lost jobs and a slower economy

If the general population in Russia knew they could move to bTC easily without repercussions from Russia they would have done it and we would all be rich by now
