Why are you trying to convert them to USD and then back again? Kinda seems like you could just connect two people trying to go opposite ways and then you'd be good.
If those two people can't connect or don't trust each other, then go to the exchanges.
I haven't known directly of any exchanged tailoring to large orders; but I've heard of private exchanges happening when bigger dollars are involved.
I don't know if it's rumors or if I'm allowed to reveal who I heard that from.
Good luck and post any public information on the topic.
Im just wondering the best way to invest in BTC and then the best way to convert back to USD at a later date. Not a way to quickly convert back and forth.
Haha, yeah you can transfer your funds to MTGox, but you will never get your USD out of MTGox. They can't handle even $10,000 being transferred out currently (been trying for a month). A lot of us believe they have a liquidity problem, but they are less than forthcoming with the reasoning.
MTGox is definitely not the place to do money conversion from BTC to USD. Probably fine the other way though if you plan on transferring your BTC out of MTGox to elsewhere, although I hear horror stories about funds being frozen coming into MTGox as fiat currency. In at least one case, the funds have been seized and are not being released even back to the originating source.
reasons like this are exactly why I dont think MTgox is a good option. Do you still consider them a viable option for converting to BTC and leaving it at that?
Surely the only other way cant be converting it in small chucks through bitcoin-otc?
