Bah. Quotes made right now are boring. Put your money where your mouth is. I use betsofbitco.in
Now OLD quotes are interesting. Here's my official prediction I made on May 11th, 2011, almost two years ago:
I have a background in trading speculative stocks, and I can tell you that this kind of speculative price explosion usually collapses back to nearly nothing eventually (thanks Timothy Sykes).
However, I have my own reasons for believing that bitcoins won't collapse, and may in fact reach the astronomical values people are dreaming about. I'm keeping those reasons to myself for now until I get a chance to gather more bitcoins.
$1000/bitcoin won't make me filthy rich, but I might be rich enough to quit my day job and devote the rest of my life to ministry, raising my kids (and maybe foster kids?), and developing bitcoin-powered websites.
I'm going to step out on a limb and make some predictions about bitcoin price increases:
1) A lot of kids with graphics cards are going to get a LOT of spending money just because they saved the few bitcoins they mined after reading about it in a forum somewhere
2) The term "bitcoin billionaire" is going to become somewhat commonplace, and will refer to someone who became a billionaire through bitcoin investment.
3) The world's first trillionaire (by USD valuation) will be one of the first big investors in bitcoins.
4) This will all happen WITHOUT the collapse of the US dollar, and without bitcoins becoming a commonplace way to pay at the grocery store.
I guess we'll see if I'm right.
Note for posterity: current bitcoin price is in the $5-$6 range after a big run-up.
I still stand by that prediction completely. Edit: actually, I'm not so sure about #4 anymore.
