at least give them a few days to make their final Dwolla withdrawals. At that point, you can be completely done with it.
Although I would LOVE for this to be the case, its just not possible. We're talking about hundrends of thousands of dollars. Should TradeHill risk all these funds and trust Dwolla when they have already screwed us?
Really? Again, assuming that Dwolla has not given Tradehill's account a complete negative balance (which they have not reported officially), how is Tradehill "risking all of these funds" by doing the following:
User A withdraws $1000 USD via Dwolla to Dwolla account xxx-xxx-xxx.
Tradehill adds $1000 USD funds to Dwolla account via bank transfer, sends money to User A.
User A withdraws money into personal bank account.
Done. Assuming Tradehill does not have a negative balance, they can do this just fine.
