Bitcoin today (USD, TradeHill)We're getting past the drama phase. That's what a useful currency is supposed to look like - flat and boring. When the chart looks like that, merchants can price products in Bitcoins. Merchants typically deposit their day's receipts in a bank once each day. If the price of Bitcoins is steady over the course of a day, merchants can convert to a real currency once a day, pull out the cash, and put it in their bank account.
There's a reasonable amount of market depth behind that, too. At first, trading on Tradehill was very thin, but now there's a a few thousand Bitcoins of market depth on both the bid and ask sides. That's not huge by financial standards, but it's enough to allow some modest real-world businesses to convert their daily take.
Back in the Mt. Gox era, we were seeing $30 and $8 in the same week. That had to stop.
This is real progress.
