I keep seeing this quote:
"Bitcoin sales on Overstock have averaged $15,000 per day, or $300,000 per month. "
Why does Overstock's month only have 20 days?
Is the Internet closed on weekends?
I think it has been an error by the writer, it's quite a lot of money that was left out of the calculation

There are a lot of Bitcoin sales on overstock, I wonder how large the bitcoin economy is at present
