Alright BTC is in a free fall. I have $X,XXX in my bank account that I'd be willing to use to buy BTC's NOW. What are my options?
MtGox used for example:
1) Dwolla - initiate ACH. Wait 3 business days. Oh yeah, and send them a copy of my ID
2) Mail cash or check
3) Liberty Reserve (similar to Dwolla sans photo ID req)
4) Paxum - wire funds to Paxum, wait 3 business days to clear. Transfer funds to MtGox
5) International USD/EUR wire - Not clear on the timeframe for this one, since it's international I'd imagine at least a few days to clear
Seems like your only option is to have funds already in MtGox/Dwolla/LR in anticipation of a crash. Otherwise you wait days. This is probably why the depth on the buy side is so low. Even if investors wanted to buy in, they're stuck twiddling their thumbs since there are no real viable options to fund quickly. This needs to be addressed otherwise there's no way to stop these crashes.
I (and American) have wired money to Tradehill three times on the way to work and used it to buy BTC by just after lunch on the same day. My bank charges me a fee, but it's flat so if one plays with several $k it's not that big a deal.
Most of the time the BTC I have bought have been back in my wallet by the evening, and into a more secure wallet by the time I've hit the rack.
I dunno if the same thing would work that way with MtGox though.
