It's only $.43 per mBTC, I feel the price is extremely reasonable and sane
I wouldn't count on it crashing. It might crash, or this might just be a bump before heading to $2000.
Historically, each run up bitcoin value has gone up tremendously. In comparison, simply going from $250 up to $450 is a relatively small jump in value.
$1 high, crash to $.50.
$32 high (60X higher than previous low), crash to $4 (higher than previous high)
$260 high (65X previous crash low), crash to $50 (higher than previous high)
$450 high? (9X higher than previous crash low point). Maybe, but I think value could potentially go a LOT higher before the next crash. If it follows past patterns, I'd expect to see a value around $2500 before crashing to around $900.
Meh, doesn't really matter to me. I think that most evidence points to the idea that simply holding your bitcoin for the next 10 years is a much better idea than cashing out at any given price.
