You think that's bad? I considered buying a ~hundred Bitcoins after the last crash, when they were going for at less than $1, but could never be bothered. :-)

Bitcoin is a form of currency that's supposed to be used. Now that so many people jump on the speculation train, and the rest mostly hold onto their bitcoins in the hope the price keeps rising, the practical viability of bitcoins can be called into question. I saw a stick of RAM for sale for the equivalent of over a thousand dollars. For a currency to rise so fast is terribly disruptive, and the rise (lack of supply in relation to demand) itself creates a vicious circle, since the faster it rises the more many bitcoin holders are tempted to further keep their bitcoins out of circulation. If the price is then calculated by only the very small portion that's up for sale (with the rest being held for often speculative purposes) - compared to a lot of prospective buyers like you who want to join the gold rush - what do you think could easily happen once some people start cashing in, the price drops, seeing the price dropping more people want to cash in, and suddenly there's a very large portion up for sale, in conjunction with a loss of interested buyers (most don't buy into a falling market, tautologically)? My advice, which I may even follow myself: buy at 100, sell at 150, never look back.
