For the record, I just sold all of my Bitcoins. I bought my first Bitcoins in June 2011 at around $28 and continued buying all the way down to $2. I actually bought about 8000 BTC around the time I made this post:

Needless to say, my return on investment was massive. We're talking 25,000% plus. For someone to see that kind of ROI today, Bitcoin would have to hit $125,000 each, or a market cap of $2.6 trillion on 21 million coins. Which brings me to my first point:
There's significantly less incentive for someone to speculate on Bitcoin today.
Yes. Buying at 2$ after a long run from 30$ is not risky at all. When you are saying you bought 8000btc that is pocket money, you involved. A couple of grands.. But today? Only 300%? That's nothing. I'll rather buy some Facebook shares.
btw: let me guess, you sold all coins above 1000$. hihi
but is Bitcoin really a good store of value if 35% of Bitcoins are held in only
500 addresses?
When you consider that 300 of this addresses belongs to me and non of them is cold storage (of an exchange or other service), then no!
