Mining capacity is way over provided.
See here Mining isn't going away in a Bitcoin resection. The big spike in Jan is not from the price but from new technology coming on board.
The business cycles you describe are a result of managed money supply, or the inability of free banks to regulate the money supply based on market conditions.
Bitcoin does away with that, the "*problem" here is herd mentality.
*The price is only a problem if you buy high and sell low, that problem is not economic it's intelligence. This market correction is a result of buying high in anticipation of deflation in a developing economy, and thinking it will happen instantly without waiting to see it mature, and then losing faith.
There is an upside to buying in early as long as all the players are educated, in that as there are a finite number of coins, it can become a store of wealth much like gold.
The downside is if you are one of the sheep that buy high and sell low.
