I'm not short bitcoin, even though I think the value of each coin will hit a couple of cents within a year as speculators flee, too many people try to mine, and another digital cryptocurrency replaces bitcoin. I choose to hold stable currencies like the dollar and other investments that are less volatile.
Bitcoin is useless as a currency (nobody would use USD if it took 5 minutes to confirm correct change, and is why nobody uses btc), will be replaced by better crypto-models (blockchain on every client, and it's absolutely gigantic, built-in deflationary currency model creates too much scarcity, and good currencies are liquid), and 95% of coins are held by speculators or the original creators.
If you honestly think you're going to make money on bitcoins or people will replace fiat currency with this, I suggest hiring an investment advisor and doing what he says (probably buy a couple of mutual funds), you are too stupid for your own good.
