To get money into Tradehill from Dwolla took ~ 20 hrs for me.
To get money into Dwolla seems to take 3 full days now.
To get money into MtGox from dwolla is only ~ 15 minutes
It seems to really approximate the old markets of the early 20th century in both size and liquidity yet with 21st century IT. If I were an academic economist, I'd be all over this shit in a heartbeat.
The delays have an impact, but the sellers on Tradehill have been very, very patient. I got 1 BTC at 7.xx and none at 5 and 6 where I loaded my measley 400 USD.
The smart move now is to get as many BTC from Tradehill and move them to MtGox if you plan to sell and rebuy.
Sounds good, but if anyone on the MT Gox site has any buy orders way above the current market value, what they should do is get on the site as fast as possible and cancel their trades.
What MT Gox should do, is not allow any trades for a while after the site is back up (people able to access their accounts), so that people with buy/sell orders aren't punished for something that is not their fault.
