A hyperbitcoinization event will be much quicker than a hyperinflation event. I have two reasons for this. First, the government will have a much greater difficulty preventing bitcoins from entering the country due to the impotency of capital controls upon it. Second, hyperinflation is inherently an attempt to fool people, whereas hyperbitcoinization is quite regular and predictable (at least by comparison). Therefore people will more easily see that they had better switch over. Thus, as fast as hyperinflation is, hyperbitcoinization will be even faster. It will happen much faster than you expect.
