The length of time for transaction confirmation is already an issue I would think. But I think it is a problem that could eventually be solved with more services. Perhaps by having an escrow service, or third party location, where people can store their BTC and have the coin already confirmed and ready to use so there is no down time? Of course the biggest issue will be security for the company that is holding those coins. For those people with much coin they would not want to leave it there long. Perhaps only put the btc in when you know you are going to spend them. That sort of thing. I am sure this has been discussed somewhere on the board though. These are just my thoughts on this.
MT.Gox said it will suspend the USD withdraw for two weeks, we are approaching that date...MT.Gox considering as a Price index so far, if they can't back to normal, another panic selling is just ahead....I guess bitstamp will be a victim of MT.Gox , we can get very cheap coins in there by that time..
